New subject: [xwiki-dev] AssertionFailure in XWiki 0.9.794

2 Aug 2005

I'm using Tomcat 5.9 with XWiki 0.9.794. When i login to xwiki it throws an error like
this,
18:14:40,479 ERROR http-8081-Processor23 http://localhost:8878/xwiki/bin/view/Ma
in/WebHome AssertionFailure:<init>:22 - an assertion failure occured (this may i
ndicate a bug in Hibernate, but is more likely due to unsafe use of the session)
