Expired Certificate in GlassFish Keystore
By pelegri on Jan 18, 2010
One of the authority certificates in the Glassfish truststore expired on Jan 7, 2010. This is generating a (verbose and somewhat scary) error message on startup. You can just ignore the message, wait - the expired root was removed in update 18 of Java SE 6 and will be removed in later patches of GlassFish Server - or...
..you can eliminate the error message now by removing the expired certificate from the keystore. Kalpana has a concise recipe on how to do this while Ron goes into more details. Original thread is here; the bug report is 6852796.
