[8u-dev] Review request : JDK-8062904: TEST_BUG: Tests java/lang/invoke/LFCaching fail when run with -Xcomp option

Konstantin,

I'd like to get an answer to my previous question:
"How reliable the test is if it ignores NoSuchMethodException & 
VirtualMachineError? Are there other manifestations of the problem?"

Most notably, have you seen VM crashes w/ -Xcomp running that test?

Best regards,
Vladimir Ivanov
