test result: Failed. Execution failed: `main' threw exception: java.lang.AssertionError: gtest execution failed; exit code = 9.


The key failure message is likely this one:

ld.so.1: gtestLauncher: fatal: libstlport.so.1: open failed: No such file or directory


Update: I started this bug in hotspot/runtime since it is a library linkage failure
and we tend to track library linkage/loading failures in hotspot/runtime.
