[cross-project-issues-dev] Hudson build error: was unable to load class

["Frank Becker (Eclipse)" <eclipse@xxxxxxxxxxxxxxx>]

Hi,

I don't know if this mailing list is the right now for my problem:

In the Mylyn Job https://hudson.eclipse.org/mylyn/job/gerrit-mylyn-tasks we have the following error in the log file https://hudson.eclipse.org/mylyn/job/gerrit-mylyn-tasks/ws/org.eclipse.mylyn.bugzilla.tests/target/work/configuration/1511852706185.log

I am not sure that this is a mylyn build issue.

Can someone help me with this issue?
