Description
A number of tests, related to classloading stressing, fail on solaris-sparc fastdebug JVM with the following assertion:

# after -XX: or in .hotspotrc:  SuppressErrorAt=/space.cpp:674]

# An unexpected error has been detected by Java Runtime Environment:
#
#  Internal Error (/BUILD_AREA/jdk6.0/hotspot/src/share/vm/memory/space.cpp, 674 [ Patched ]), pid=18322, tid=3
#
# Java VM: Java HotSpot(TM) Client VM (1.6.0-rc-fastdebug-b62-debug interpreted mode)

EVALUATION Duplicate of 6272221. The script attached here reproduces the problem consistently. Key is -client -Xint, it doesn't fail with -server -Xint.
