Sun Bug report – (english post)

For those english readers, who have been visiting this blog through

google, I wrote a english version (resumed).

 I submitted a bug
report to Sun, about the usage of J2SE 5 -Xshare:on feature and Linux

kernel 2.6.9. At this moment, it was classified as “request for

enhancement”.

The issue happens if you have been using J2SE 5 -Xshare:on under Linux

kernel 2.6.8.1 (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.
