Maven Throws "java.lang.OutOfMemoryError" when generating Sure-fire reports

Question

I know this question appeared all along long time, but none of the solution worked successful to me

Maven throws "java.lang.OutOfMemoryError"

How to deal with "java.lang.OutOfMemoryError: Java heap space" error?

though I tried above two solutions, and also tried other options suggested by other answers still I was ended up in the below error

to make it clear,

I have used sure-fire to run the testng tests and generate the report accordingly... so I first applied the approach to add the argline, it doesn't help. then I tried adding MAVEN_OPTS and increased values ranging from 256 to 1024 that doesn't works either finally added JAVA_TOOL_OPTIONS, still it doesn't works even though i tried multiple values to specify

Are there any other choices left to try out to resolve the problem

Don't mark this duplicate... I need a better solution than already existing.

surefire plugin start separate process, it have its own java options. See Eugen Covaci answer to change them. — talex, Dec 18 '18 at 07:58
I did that, btw it was already listed solution... still it doesn't works — Amutheezan, Dec 18 '18 at 08:00
Try to increase memory limit even more. Also check that you can run test in your IDE. Maybe it is actual problem with them. — talex, Dec 18 '18 at 08:02
I check error message again. It says that it can't create new thread. You may want to limit amount of created thread. As temporary solution you can try to reduce stack size by `-Xss256k` (may lead to stack overflow exception). — talex, Dec 18 '18 at 08:06
i was able to try it in my ide as well as my local windows system. this problem occurs when i tries to run in linux server.... — Amutheezan, Dec 18 '18 at 08:07
Your linux may be configured with some limit on number native thread per process. Execute `ulimit –u` on your linux machine to get the limit. — talex, Dec 18 '18 at 08:08
Looks good. So you have to find out why so many thread created. I can't help you with that, you need to inspect you code. — talex, Dec 18 '18 at 09:05
Please post the relevant hardware/software for that linux server. (Cpu, memory,linux distro,kernel params) etc — , Dec 18 '18 at 10:31
Not enough. Run the following commands: `cat /proc/meminfo` and `vmstat -s` — , Dec 18 '18 at 11:51

You can configure the maven-surefire-plugin like this:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>x.x.x</version>
    <configuration>
        <argLine>-Xmx2048m -XX:MaxPermSize=1024m</argLine>
    </configuration>
  </plugin>

to set JVM arguments.

`ignoring option MaxPermSize=1024m; support was removed in 8.0` and got the following error – Amutheezan Dec 18 '18 at 07:50

@AmuD7 Remove `-XX:MaxPermSize=1024m` part it is not supported in your version of JVM (it is removed in 8.0). – talex Dec 18 '18 at 08:00
yeah I tried both choice with and without `-XX:MaxPermSize=1024m` still it end up in the same errors – Amutheezan Dec 18 '18 at 08:01

Note that the exception shown is not necessarily a heapspace-issue (although it might be because of a heap that is *too large*) but rather a shortage of OS-resources. – piet.t Dec 18 '18 at 08:14
