Summary: The test case uses reflection to invoke method call in 
recursive caused SEGV, which should be StackOverflowException. It only 
happens with product binary.  This fix changes the default 
StackShadowPages on solaris x86 platform.  Note this is for jdk7 update 
release (only).

Tests: JPRT, test case which reported the crash, and JTREG
