RFR: 8019779 JDK 8 build failed due to hotspot crashed on Solaris 10u10 sparcv9/sparc with SS12u3 compiler

[Vladimir Kozlov]

Lois,

Usually such problems happened only with fastdebug build. You lowed optimization level for product and optimized builds. 
Did it also fail with these versions? Sorry, I can't see bug report.

Also you kept lower opt level for jvmtiClassFileReconstituter.o (\>= 510). Does it still have problem with SS12u3?

Thanks,
Vladimir
