I see the exact same error while running SWTBot tests with latest eclipse (eclipse-2020-09), openjdk 11.0.7 inside docker ubuntu 18.04 image, the error log is 

21:39:09  java.lang.NullPointerException

it crashes eclipse and the test fails, is there any fix for this?

For this bug, comment #0 was not relevant. It was comment #1 causing the issue and got solved in bug 567052.

Is this fix available in eclipse 2020-09? because I see the issue with eclipse 2020-09

The OOM issue was JDT tests specific and only present in a separate BETA_JAVA15 branch until 2020-09. 

So, this bug and hence the fix is not related to Eclipse 2020-09.

Sorry I am a bit confused, I am talking about the NullPointerException error This error was not present with previous eclipse while running SWTBot tests but with eclipse 2020-09 I see this issue and it crashes eclipse during tests execution

As mentioned in comment #4, this bug is not about the NPE but about the OOME in JDT tests. Please open a bug in Platform UI for the NPE issue.
