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
17-Dec-2018 11:36:54 Exception in thread "ForkJoinPool.commonPool-worker-5" java.lang.OutOfMemoryError: unable to create new native thread

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.
