Problem:
Confluence 2.8.0 didn't start up on Websphere 6.1 (extact version is 6.1.0.9).
In the logs the following can be found (see also attached log snippet):
creating bean with name 'sessionFactory' defined in class path resource [productionDatabaseContext.xml]: Invocation of init method failed; nested exception is java.lang.LinkageError: LinkageError while defining class: javax.managemen t.MBeanServer [...] java.lang.ClassFormatError [...] at com.mchange.v2.c3p0.management.ActiveManagementCoordinator.attemptManageC3P0Registry(ActiveManagementCoordinator.java:52)
The problem could be tracked down to the JMX bean, that c3p0 tries to start internally in file ActiveManagementCoordinator.java, line 52.
Workaround:
Since this problem did'nt occur with Confluence 2.7.2 (the last version I installed), I simply replaced the c3p0-0.9.1.2.jar in Confluence-2.8 with the c3p0-0.9.0.4.jar from Confluence 2.7.2.
This solved this problem and the confluence start up went on up to the very same problem as reported in CONF-11434 for Weblogic (same workaround for this works on Websphere 6.1.0.9).
