RFR 8057696: java -version triggers assertion for slowdebug zero builds

[Severin Gehwolf]

Hi,

Can someone please review and sponsor this tiny change?

Bug: https://bugs.openjdk.java.net/browse/JDK-8057696 (Thanks Omair for
filing it for me)
webrev:
https://fedorapeople.org/~jerboaa/bugs/openjdk/JDK-8057696/webrev.0/


As mentioned in the bug, the change as introduced with JDK-8003426
removed some Zero code in cppInterpreter_zero.cpp.
(AbstractInterpreterGenerator::generate_method_entry). In this code
block was an explicit call to generate_normal_entry() using a param
value of false unconditionally (regardless of synchronized == true or
not). After the JDK-8003426 change the generate_normal_entry() function
get's *correctly* called with true or false values. However, it renders
the assertion incorrect. The fix is to get rid of the offending
assertion.

Thanks,
Severin
