A number of JPRT tests fail when the VM is submitted with the -XX:+CheckUnhandledOops flag for testing.

Submit command: 
jprt submit -n -tf -XX:+CheckUnhandledOops -noquickabort -ot '.*fastdebug.*'

Fails the following test targets:

  solaris_sparcv9-fastdebug-c2-jvm98 solaris_i586-fastdebug-c1-jvm98
  solaris_i586-fastdebug-c2-jvm98 solaris_i586-fastdebug-c1-scimark

  solaris_i586-fastdebug-c1-scimark_3 solaris_i586-fastdebug-c2-scimark_3

There are a couple of SIGSEGVs and SIGBUSs, but most of the failures are an assertion:

N/A

It is caused by Sun Studio 11 C++ compiler bug 6629277 "destructor call for temporary object in switch statement missing in some cases in Studio11".   Bad code is generated for DepChange::ContextStream::next() in dependencies.cpp.  A simple workaround is to enclose the offending switch statement clause in curly brackets.
