Trying to run spark application which I build using maven and jdk1.8 on a remote machine in which installed Java version: jdk 1.7.
Using spark-submit command:
./bin/spark-submit --class myapp.Main --master local[*] /home/mbala/myJars/CDCJar/myapp-0.0.1-SNAPSHOT.jar /home/mbala/myJars/CDCJar/previous.csv /home/mbala/myJars/CDCJar/source.csv /home/mbala/fer
Getting below exception:

If you build a Java program with a Java Development Kit 8, you need a Java Runtime of at least 8 to be able to run it, otherwise you get this exception. Upgrade the version of java on your remote machine or build with a JDK 7 instead to avoid such kind of issue.

Getting this error when trying to run JavaFX program. Does it have something do do with what version of Java i'm running on Eclipse? Current running jdk-11.0.2 and maybe running it on 1.8 would do the trick.

As mentioned in official release notes of JDK 11
JavaFX is no longer included in the JDK. It is now available as a separate download from openjfx.io.
Yes, running on JDK1.8 would do the trick. But make sure to use Oracle JDK 1.8 and not OpenJDK 1.8. (You can get JavaFX to work on OpenJDK, but it'll be an extra hassle)
I have some problems when deploying my app with JBoss eap 7.0.0
The app is compiled using Java 1.8 revision 121, and also the JBoss is launched with the same JDK.
The error is the following:

Does anybody have some information about what's happening? It seems like the error is in a module that is not from the application, but from any JBoss library (org/jboss/modules/Main)

Not being able to run your own stuff might be very frustrating. It is due to Java version mismatch i.e. you're trying to run code compiled with higher version of Java on lesser version of runtime.
Remember to always use the latest version of JMeter and the latest version of Java (choose 64-bit Server JRE or JDK for your operating system).
You're also welcome to check out 9 Easy Solutions for a JMeter Load Test “Out of Memory” Failure guide for other recommendations on tweaking JMeter for maximum performance.
Plugin requires Java 7 to run even with Apache JMeter 2.13.
So ensure you use a Java 7 or Java 8.
Besides, if using Java 8, ensure you use a JMeter 2.12 or superior as JMeter is compatible with Java 8 only starting from this version.
I just downloaded a grails project from svn.
I saw that the unsupported major.minor version is a well known problem on S.O. caused by a mismatch version of JDK used during runtime and compile time.
But I am using the very same version as below:

Installed JRE:
Please what am I missing for still having the below error?

Compilation error: java.lang.UnsupportedClassVersionError: com/sun/tools/javac/Main : Unsupported major.minor version 52.0
I run it via rightclick on project -> run-as -> grailsCommand (run-app)
The project was compiled using a newer version of JDK but is being run at an older version. Clean all your code and rebuild the project.
Sometimes this is due to a plugin whose binary has been compiled with a higher version of Java.
I fixed it by using the appropriate groovy version for grails version I have.
You can find the link here.
For instance, grails 2.3.9 -> groovy 2.1.9
I also made sure to use the right Java version based on grails.project.target.level in BuildConfig.groovy. For me, it is 1.7 (java 7)

I am trying to run Java 1.8 Map Reduce Job over AWS EMR. I have set compile compliance and JRE version as 1.8. But still its giving following error while running.
Since I am using one stanford API I cannot switch to lower Java versions. Could some one please help me here.
