Problems in C2 on ppc64/ppc64le due to CompactStrings

Hi,

we are currently facing some problems in the C2 compiler on ppc64/ppc64le
which are caused by the integration of the new CompactStrings feature. The
errors manifest in various, mostly string related Java errors or
NULLPointer exceptions. Running with '-Xcomp' will also result in an
immediate crash.

We are currently working on a fix for this problem but until we find it you
can workaround the problem by using the XX:-SpecialStringEquals option.

Regards,
Volker
