[~kvn] Vladimir, I agree this test should be put into graal specific problem list and then the bug can be closed as dup.
04-07-2018
Closing as duplicate.
04-07-2018
I think we should put the test into ProblemList-graal.txt and close this bug as duplicate of JDK-8202124.
03-07-2018
I am tempting to close this bug as duplicate of JDK-8202124. [~iignatyev] Igor what do you think?

Also such test should have -XX:+PrintCompilation to help diagnose issue.
03-07-2018
In addition to pre-initializing Graal we need to allow Graal methods compilation regardless compileonly command.

Actually it is the same issue as JDK-8202124 because of compileonly. Looking on the test output and it say method was not compiled and is in queue: Warning: private int compiler.whitebox.DeoptimizeFramesTest$TestCaseImpl.method() is still in queue after 10798ms java.lang.RuntimeException: should be the same nmethod: expected 61 to equal 62 Also test run with Tiered compilation. Method should be compiled 2 times - one with C1 and second with Graal (or C2). Based on output above Graal's compilation is still in queue as result first NMethod.get() will return result of C1 compilation. By the time second NMethod.get() is executed the method was compiled by Graal and you get different ID.

Could be the same issue as JDK-8205400. JVMCI and Graal needs to be pre-initializzed by adding -XX:-BackgroundCompilation flag. The test also use compileonly command which prevents Graal's methods compilation which may significantly delay compilation.
03-07-2018
ILW = MMH = single DeoptimizeFramesTest failure because delayed compilation!; with Graal; none = P3 Can this be duplicate of JDK-8202124?
