[9] RFR(S): 8139380: VMError::report_and_die() does not produce replay file

[Zoltán Majó]

Hi,


please review the patch for 8139380.

Bug: https://bugs.openjdk.java.net/browse/JDK-8139380

Problem: The test compiler/ciReplay/TestVM.sh intentionally crashes the 
VM and expects compiler replay data to be saved into a file 
('test_replay.txt'). Since the JVMCI changes were pushed, the test fails 
on some platforms we support because the file is not created by the VM.

The file should be created by VMError::report_and_die(). However, a 
SIGSEGV is thrown in VMError::report() (report() is called by 
report_and_die()) that causes the VM to exit without saving replay data.


Solution: Update VMError::report() to use an appropriate format string 
to print the VM version in both JVMCI-enabled builds and builds without 
JVMCI.

Webrev:

Testing:
- JPRT (testset hotspot);
- executed failing test on all supported platforms, the failure is not 
triggered.

Thank you and best regards,


Zoltan
