I just recently upgraded to Hudson version 1.322 (previous version used was
1.316). This was the first time that I used the Hudson admin feature to install
the Hudson upgrade (don't know if this matters, but it was the first time I used
this feature).

I started seeing failures in the Subversion polling log. This problem blocks
the respective build job which is reporting the problem with Subversion polling.

I will include the Subversion polling log at the end of this note.

The version of the installed Polarion plugin is 1.1

I have one slave build node set up for the Hudson installation. The slave jar
used for the slave node was taken directly from the hudson.war for the current
version (1.322).

When I disable the Polarion plugin, Subversion polling returns to its normal
behavior, the Subversion polling log appears normal and the Hudson job runs again.

Here is the Subversion polling log when the problem occurs.
