7.0.6 NPE in cluster syncing

Hi,

Today I upgraded Tomcat from 7.0.5 to 7.0.6. Now I have these errors in de logs.
Jan 14, 2011 4:24:50 PM org.apache.catalina.ha.tcp.ReplicationValve sendReplicationMessage
SEVERE: Unable to perform replication request.
java.lang.NullPointerException
        at org.apache.catalina.ha.tcp.ReplicationValve.isRequestWithoutSessionChange(ReplicationValve.java:554)

And I loose my session when the loadbalancer sends me to another server.

Can these happen because I have migrated sessions from 7.0.5 to 7.0.6 while upgrading one node at a time? Or is this a bug in 7.0.6?

Ronald.

Yes, it is a bug. I fixed it,
https://issues.apache.org/bugzilla/show_bug.cgi?id=50591

Note, that ReplicationValve has changed in 7.0.6 (compared to 7.0.5
and 6.0.x) and the filter attribute now accepts a single regexp. The
';' is no more treated as separator in the value of "filter" attribute
of ReplicationValve. Use '|' instead.

This bug was a regression from implementing this new "single regexp" feature.

Best regards,
Konstantin Kolinko
