Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Integrate javamelody 1.50 into atlassian stash 2.12.0 
(https://www.atlassian.com) by installing jar/war and modifying web.xml
2. Try to create a new repository within stash
3. Failure: HV000041: Call to TraversableResolver.isReachable() threw an 
exception

What is the expected output? What do you see instead?
Expected creation of new repository - above error is shown instead.

Removing javamelody from stash again, stash works correctly again

What version of the product are you using? On what application server, JDK, 
operating system?
Tomcat delivered with STASH 2.12.0 on Java 1.7, Win 2008Server Sp1

Forgot to say: Monitoring pages within stash have been showed correctly 
(without error)

This is an issue probably since v1.50.

So you can try v1.49 as work around:

It's fixed in trunk (revision 3781) and ready for the next release (1.51).
Thanks.
