Hi Paru, It looks good. Thank you a lot for taking care about this! Could we get at least one more review from the Serviceability team on this new test? Thanks, Serguei On 2/2/18 09:35, Paru Somashekar wrote: Hi, Please review the fix for JDK-8193150. The fix introduces a new jtreg test, NashornPopFrameTest. It is based on the original test from JDK-8187143 that was provided by the customer. Bug : https://bugs.openjdk.java.net/browse/JDK-8193150 Webrev : http://cr.openjdk.java.net/~psomashe/8193150/webrev/ Here is a brief description of what the test does :- * The debuggee,  creates and uses a Nashorn engine to evaluate a simple script. * The debugger  tries to set a breakpoint in Nashorn’s internal DEBUGGER method. * When the breakpoint is reached, it looks for stack frame whose method's declaring type name starts with (nashorn dynamically generated classes) ”jdk.nashorn.internal.scripts.Script$”. * It then pops stack frames using the ThreadReference.popFrames() call, up to and including the above stackframe. * The execution of the debuggee application is resumed after the needed frames have been popped. This test is included in the ProblemList as it fails under some circumstances (bug JDK-8187143). Is always passes with the -Xint flag however always fails with -Xcomp. It fails intermittently with the -Xmixed (default). thanks, Paru.
