I have observed this problem with Netty version 4.1.15.Final but not with 4.1.13.Final. Check your transitive dependencies. I.e Spring Boot references Netty.
What I added to POM to make it work with Spanner API version 0.22.0-beta:
<properties>
<v.netty>4.1.13.Final</v.netty>

If the problem persists, or if it is not an option, plase run your JVM with appropriate bootclasspath entry, like:
java -Xbootclasspath/p:/tmp/alpn-boot-8.1.11.v20170118.jar -cp ...
Make sure to replace /tmp/alpn-boot-8.1.11.v20170118.jar with location of alpn jar that matches your JVM version as listed on this page: https://www.eclipse.org/jetty/documentation/9.4.x/alpn-chapter.html

There is a possible solution on github: "Exception when configuring SSL: "Jetty ALPN/NPN has not been properly configured."
The recommended steps, quoting from the above document:
1) Edit catalina.sh
/usr/local/Cellar/tomcat/8.5.3/libexec/bin/catalina.sh
2) At line 103, add the following
CATALINA_OPTS="-javaagent:/Library/Tomcat/lib/jetty-alpn-agent-2.0.6.jar"
3) Restart tomcat
../bin/shutdown.sh ../bin/startup.sh

java.lang.NoClassDefFoundError: Failed to link org/pentaho/di/core/attributes/metastore/EmbeddedMetaStore

I'm building a batch with Pentaho Kettle to process some files. This batch is started by a servlet. However, when I try to start it, I get the following warn which actually block the process:

However, when I look in my lib folder, the jar containing this class (kettle-engine-8.2.0.0-342.jar) is there and the class is also in it.
I'm using a JBoss EAP 7.0 with Java 1.8.0.161 on my computer for development. I start it with my IDE (Eclipse Photon). Here are my dependencies in the pom.xml:

Important : this issue does not occur when using previous version of kettle-core and kettle-engine (tested with 7.0).
It's an embedded call so I do not directly call this class in my code.
I do not have multiple versions of this jar in my classpath.
Another person in my company found out so i'll just answer here to close the topic.
I didn't show it here but in my dependencies I had a dependency to some custom framework from work. This framework actually included pentaho, but the 7.0 version. Then, #suresh was right when he talk about multiple version jar.
So the answer is :
Check if any dependency actually contains duplicate dependency you're calling somewhere else. To avoid this issue, use the excluding syntax in the dependency calling the wrong versions :
<exclusions>
<exclusion>
<groupId>pentaho-kettle</groupId>
<artifactId>kettle-engine</artifactId>
</exclusion>
<exclusion>
<groupId>pentaho-kettle</groupId>
<artifactId>kettle-core</artifactId>
</exclusion>
</exclusions>

seems like you mix netty 4.1 and 4.0. You need to only use 4.1 if you want to use pushy.
Did you clean your classpath in between I created a test project containing only the dependency
<dependency>
<groupId>com.turo</groupId>
<artifactId>pushy</artifactId>
<version>0.10</version>
</dependency>
and a simple main class just creating the client with the snipped you are using above and it works out fine
To me it looks like there might be two versions of BootstrapConfig on the classpath. Try to remove all dependencies besides pushy and clean/refreshing the maven dependencies.

Update
I've moved those jackson dependencies into <dependencyManagement> section of my pom.xml file,
<dependencyManagement>
<dependencies>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.8.5</version>
</dependency>
<dependency>

</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>2.8.0</version>
</dependency>
</dependencies>
</dependencyManagement>
according to maven documentation ,no matter which version of library jackson-core is requested by a dependency, version ${jackson.version} will always be used, still my codes works in local ,but in that test server
the the exception remains same, even if I deploy my war file in that test server code throws the same exception.
most likely you have compiled your code against a different version of the class, than the one you are using when running it.
Please make sure that on the environment where you run the code there is no any other version of jackson-databind dependency on your classpath.
finally solved the issue , I found that glassfish 4.1.1 has a very old version 2.3.2 of jackson-core jackson-annotation and jackson-databind, so we decided to use Payara server that uses fairly latest version of jackson jackson 2.8.5 and tested the no such method error is solved, the code works fine in that Payara server
Update:
glassfish version 5.0 uses updated version jackson 2.8.9 , I think using that will solve this issue too
Probably one of your other artifacts depends on different version of databind. You can try to exlude it explicitly from each of them to guess
<dependency>
...
<exclusions>
<exclusion>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
</exclusion>
</exclusions>
</dependency>
Please check version.
Screenshot:
For me, I encountered the same exception due to lower version of jackson-databind:
From:
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.5.0</version>
</dependency>
Changed to:
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.8.9</version>
</dependency>
I just update my pom.xml file with higher version of jackson-databind.
Then right-click Project --> Update Maven Project and the exception is resolved.
<!-- faster JSON -->

Embedded Neo4j SPI Class (lucene PostingsFormat) Error

I've embedded Neo4j 3.0.1 into a Java 8 application, but I've been running into SPI issues.
Running from within IntelliJ produces the correct results as expected, but as soon as I build the artifact to a JAR, run it and attempt to write to Neo4j, I get the following exception:
Caused by: org.neo4j.kernel.impl.store.UnderlyingStorageException: java.lang.IllegalArgumentException: An SPI class of type org.apache.lucene.codecs.PostingsFormat with name 'BlockTreeOrds' does not exist.

How do I resolve this issue?
UPDATE:
I've re-created this issue with a really simple blank project, source can be found here if you'd like to run it on your end: https://github.com/SeanNieuwoudt/neo4j-spi
I took your project and executed in my eclipse. I have no issues. Here are below console logs after starting:
[Thread-0] INFO org.eclipse.jetty.util.log - Logging initialized #473ms
[Thread-0] INFO spark.embeddedserver.jetty.EmbeddedJettyServer - == Spark has ignited ...
[Thread-0] INFO spark.embeddedserver.jetty.EmbeddedJettyServer - >> Listening on 0.0.0.0:8080

[Thread-0] INFO org.eclipse.jetty.server.Server - Started #772ms
While accessing - http://localhost:8080/
I got output printed as 'Hello World"
Steps i followed:
1) Downloaded your project from your github url
2) Imported as maven projects pointing to java 8
3) Maven install was successful
3) Ran main class
4) Saw the output in the browser.
Am i missing any steps to replicate actual issue?
Or is something to do with your maven. May be check your maven dependencies after running maven install to see if the expected jars are downloaded.
Good luck.
Try to add the following dependency:
<dependency>
<groupId>org.apache.lucene</groupId>
<artifactId>lucene-backward-codecs</artifactId>
<version>5.5.0</version>
</dependency>
This is my solution. https://stackoverflow.com/a/38623295/6579110. You can also check https://maven.apache.org/plugins/maven-shade-plugin/examples/resource-transformers.html#ServicesResourceTransformer for more details.

Hadoop 2.6.x and Amazon AWS SDK Library conflicts http-core conflict

My job writes each record to DynamoDB in the Hadoop's map.
I cannot make it run with Hadoop 2.6 which has httpclient-4.2.5.jar and httpcore-4.2.5.jar.
AWS which I am using was built using httpclient-4.5.2.jar and httpcore-4.4.4.jar.
When I am using classpath to include the new jar files, it gives the following exception.
java.lang.Exception: java.lang.NoSuchFieldError: INSTANCE
at org.apache.hadoop.mapred.LocalJobRunner$Job.runTasks(LocalJobRunner.java:462)

at com.amazonaws.http.apache.client.impl.ApacheHttpClientFactory.create(ApacheHttpClientFactory.java:49)
To me, it looks like Hadoop was built using the old libraries and something has changed in the syntax.
What's the reasonable solution than recompiling older sources of AWS?
As an update, I had to switch to Maven and play around with the versions a bit.
