If solaris-amd64 java is started with -XX:+StartAttachListener and later core file is produced, then none of troubleshooting tools work on this core file:

$ jstack -J-d64 jdk/bin/java core
Attaching to core core from executable jdk/bin/java, please wait...
Error attaching to core file: can't open shared archive file /tmp/a/jdk2/jre/lib/amd64/server/classes.jsa

EVALUATION UseSharedSpace is a bool type and in SA its value is read as int. It should be changed to read a byte value. See saproc.cpp line 579 (it may change).
