MySql errors under Tomcat

[dhowe01]

using Sonar 1.11.1
This error occurs often, and the system crashed over the weekend.

Begins like this:

2009.10.30 17:17:13 INFO  org.sonar.INFO  loading pmd profiles...

e the thread which caused the illegal access, and has no functional impact.
java.lang.IllegalStateException
        at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoa

and this over the weekend:

It's as if Sonar is no longer able to see the mysql connector jar??


Seems similar to this previous bug: http://jira.codehaus.org/browse/SONAR-391
and to this non-sonar issue with mysql/tomcat: http://stackoverflow.com/questions/1562244/mysql-j-connector-unloads-mysteriously-under-tomcat-6-jdk-6

Hello,

Could you first try to download a fresh jdbc driver from the mysql web site and replace the old one. Indeed looks like the jar is slightly corrupted.

Thanks
Freddy

Seems identical to this previous bug:
