Also the following question applies to this issue, Should this kind of CPU intensive test need to run in a separate VM? I am not sure but is there any possibility that such kind of test can crash the VM?

It looks to be the mathematical calculation required to generate primes for DSA parameters are taking long enough which makes the test timeout. One possible solution could be instead of processing all supported parameters in one single @run, divide each test parameter to run with each @run tag along with fixed timeout period configured based on the case requiring time to complete. Ex: (3072, 256) is taking almost double of time what (2048, 256) takes.

JDK-8157898 has similar issue so I will assign this bug to myself.
