I'm trying to do unit test to my java GUI source code in Eclipse.
When I execute unit test with jUnit, all of my test succeed.
However, I encountered a small exception in SonarQube report as well as my tests which was successful in eclipse are reported all failed.
Exception messages are here.
No X11 DISPLAY variable was set, but this program performed an operation which requires it.
java.awt.HeadlessException:

What should I do?
You have to move your Sonar/test server to the same environment where it will run eventually - Windows in your case. See, AWT uses platform GUI environment. So, it takes graphical parts from the system. In other words - Label on Windows looks different then on Mac and different on Unix. In last case Unix may have no Graphical environment at all and so you will have no Label too. Headless allows you compile and run "graphical" environment without platform support.
I installed xvnc plugin in jenkins, and vnc4server in my server.
then it is completely solved.

This problem arises when consumers want to get the zookeeper value of the local Linux virtual machine
I used Springboot 2.1，Zookeeper is on the local Linux virtual machine. I've seen a very close answer, but I don't know how to set it up. The address is https://blog.csdn.net/chenxiaochan/article/details/78776304. What he means is that the IP of the server published by the Dubbo service uses DHCP, not static. And through his method, I queried my own ip, which is really different from the IP registered in the registry.
I've also tried to disable virtual network cards, but It means I can't connect to the local Linux virtual machine.
My provider application.properties
dubbo.application.name=provider-ticket
dubbo.registry.address=zookeeper://192.168.248.132:2181
dubbo.scan.base-packages=com.cq.providerticket.service
My consumer application.properties
dubbo.application.name=consumer-user
dubbo.registry.address=zookeeper://192.168.248.132:2181
dubbo.consumer.check=false
dubbo.registry.check=false
server.port=8081
dubbo.protocol.host=192.168.248.132
dubbo.provider.host=192.168.248.132
linux dokcer command
docker run --name zk01 -p 2181:2181 -p 20880:20880 --restart always -d zookeeperID
This is the Exception it reported.

If you use docker in linux virtual machine, linux system is run in virutal box or VMware Workstation
ssh to linux
vim /etc/sysconfig/network-scripts/ifcfg-eth0 or ifcfg-eth33 file
change the BOOTPROTO=dhcp to BOOTPROTO=static and set IPADDR=192.168.248.132
make sure 20880 and 2181 port is open through firewall
If you use docker for windows,linux virtual is in hyper-v, 192.168.248.132 is your windows computer ip
set the dubbo.registry.address=zookeeper://localhost:2181
set the dubbo.protocol.host=localhost and dubbo.provider.host=localhost

I have set encoding as so
[ compileJava, compileTestJava ]*.options*.encoding = "utf-8"
allprojects {
// This is for getting the revision number to use in our final build
ext.project_version = 'r' + "$svntools.version"
tasks.withType(JavaCompile) {
options.compilerArgs += ['-Xlint:deprecation']
options.encoding = "utf-8"
options.fork = true
}
}
But it doesn't seem to affect it. The test runs fine when tested in ant using UTF-8 encoding. As far as I can tell both lines are exactly the same so I am sort of at a loss here.
Any help would be greatly appreciated.
--- UPDATE ---
Looking into the file that it reads from the apostrophe is with in html and is represented by it's acsii code #146;
I am not sure why this would be an issue if encoded properly but I suspect it is the issue.
Thanks
After further investigation the issue was with a dependency. jericho html in gradle was 3.3 and in ant it was 3.0. Downgrading the dependency in gradle resolved my issue.
Env:
Java
Maven 3.5.2
JUnit 4.12

I have some test cases here

Travis config:
language: java
jdk:

The question is I test successfully with mvn test on local machine
I commit to github, after it ran the test, oraclejdk 8 won't error,
but openjdk7 will all failed with these three test cases.
The log is here, I stamp one of three, the error are same:

How can I fix it, or don't do the test with openjdk7?
I find some problem on my code
I need to tear down all my objects because the test runner is context-switch, which means it many run the test while it may switch to another test, so this make my test fail.
One of my test cases is getting NoSuchMethodError. I've removed getExceptionHandler() method from the project so this method shouldn't be detected at all. This is the only test case with this error.
Here is the stack trace

I don't know how to tell the compiler that getExceptionHandler() doesn't exist any more.
Thanks
The problem is not in your test! The test calls ISOPPCServiceHelper which still uses the method getExceptionHandler(). You have to recompile that class. Always use clean test of your build system after refactorings to make sure everything is compiled right (hopefully you have one, otherwise rebuild project of your IDE should do the job).
In Java I am using FutureTask to run a Callable asynchronously via Executor. In order to check if an error occurred from the calling thread, I need to throw potential exceptions from the Callable. This however, leads to the stacktrace printed out to System.out (I debugged and this happens inside Unsafe.unpark(Thread) from LockSupport.unpark(Thread)).
Any ideas how I could prevent this?
I already log the exception to a real logger before (via SLF4J) and never want direct stacktraces on System.out.
Update: I think I already pointed out the relevant information but to clarify all the questions:
This test case can reproduce the Problem (Method testTransferStreamAsyncCallbackFail()):
https://github.com/m-m-m/util/blob/master/io/src/test/java/net/sf/mmm/util/io/base/StreamUtilTest.java
The implementation used is this:
public AsyncTransferrer transferAsync(InputStream inStream, OutputStream outStream, boolean keepOutStreamOpen, TransferCallback callback) {
StreamTransferrer transferrer = new StreamTransferrer(inStream, outStream, keepOutStreamOpen, callback);
AsyncTransferrerImpl task = new AsyncTransferrerImpl(transferrer);
this.executor.execute(task);
return task;
}
I debugged through the eniter code and it is definetly not my code that logs to the console. This is done in the JDK as I tried to explain.
Additional Update to answer the questions:
The executor I am using is Executors.defaultThreadFactory()
As you can see here:
https://github.com/m-m-m/util/blob/master/core/src/main/java/net/sf/mmm/util/concurrent/base/SimpleExecutor.java#L30
https://github.com/m-m-m/util/blob/master/io/src/main/java/net/sf/mmm/util/io/base/StreamUtilImpl.java#L165
The output is the stacktrace of the Exception that I throw in my test from the Callable:
java.util.concurrent.ExecutionException: net.sf.mmm.util.io.api.RuntimeIoException: IO: An unexpetected error has occurred while copying data!
