Got VM crash during Appserver compatibility testing using -server option for 
domain in Appserver. (or -d64 on Sol sparc v9, but such option also cause server VM
 invocation ). It looks like it happened during domain starting, but not every domain start caused VM crash.
With -client option ( install defaults for Appserver ) all OK.
Also on JDK 1.5.0_11, b03 with -server option all OK, no VM crash on the same hosts/OS.
