During the code review for the following fix:
JDK-8227117 normal interpreter table is not restored after single
stepping with TLH
Erik O. noticed a potential race with templateInterpreter.cpp: copy_table()
depending on C++ compiler optimizations. The following bug is being used
to fix this issue:
JDK-8227338 templateInterpreter.cpp: copy_table() needs to be safer
Here's the webrev URL:
This fix has been tested via Mach5 Tier[1-3] on Oracle's usual platforms.
Mach5 tier[4-6] is running now. It has also been tested with the manual
jdb test from JDK-8227117 using 'release' and 'fastdebug' bits.
Thanks, in advance, for questions, comments or suggestions.
