Hudson: Error after creating doxygen files; downgrade not working either

I'm having the following problem with Hudson after upgrading to 2.1.0:

After successfully creating the doxygen output, the following exception occurs:

Publishing Doxygen HTML results.
The determined Doxygen directory is 'C:/doxy/myDir'.
FATAL: error
hudson.util.IOException2: java.io.IOException: Unconnected pipe

The error did not occur with 2.0.1, unfortunately, downgrading does not work - Hudson tells me, that it can't read the job files anymore.

Does anyone know the best way to deal with this? Is there a simple solution to either make the doxygen plugin work in 2.1.0 or to successfully downg开发者_如何学运维rade to 2.0.1?

Not sure what exactly the problem was, but migrating to the newest Jenkins release and using the HTML report publisher plugin instead of the Doxygen plugin is at least a work
