Hi all,
java/lang/StackWalker/LocalsAndOperands.java runs LocalsAndOperands 3 times with following set of jvm flags:
- -Xint -DtestUnused=true
- -Xcomp
- -Xcomp -XX:-TieredCompilation
When running with Graal as JIT (-XX:+TieredCompilation -XX:+UseJVMCICompiler -Djvmci.Compiler=graal) 3rd scenario could take more than 10 minutes and the test could fail by timeout. Actually running LocalsAndOperands with Graal and with "-Xcomp -XX:-TieredCompilation" doesn't provide big benefit and it would be reasonable to disable this scenario in case Graal is enabled.
Please review the change.

thanks, -katya
