The issue happens if you have been using J2SE 5 -Xshare:on under Linux
kernel 220.127.116.11 (or versions below it), and switch to kernel 2.6.9. When
using -Xshare:on option again, the JVM will try to use the shared
archive created under a different memory layout. See the bug report.
To solve the problem, just run the JVM with -Xshare:dump option. That will
regenerate the shared archive.
