A new vm argument type, 'uint64_t', was added as part of 6887571. The jdk library
code in jdk/share/native/sun/management/Flag.c that fetches all the vm product flags
throws an exception if it doesn't understand the type of an argument. The change
for 6887571 didn't include full serviceability support for uint64_t.
This bug affects the following SDK/JDK test in the MM_REGRESSION
Add serviceability support for uint64_t.
A new vm argument type, 'uint64_t', was added as part of the fix for 6887571, but
full serviceability support wasn't done in the vm. The jdk library code in
jdk/src/share/native/sun/management/Flag.c throws an exception if it doesn't
understand the type of a vm argument, hence the problem.
*** (#1 of 1): [ UNSAVED ] ###@###.###
If a flag has a type unknown to the jdk library, then assert in debug builds and ignore it in product builds.
