**First thing I tried of course was changing the memory settings. However this did not work. No matter how high I set it, it would always give this error.

Solution:

1. This happens in tomcat versions higher than 7.0.33, so downgrading could be one possible solution.

2. jaxen and dom4j don’t play very well together, upgrading to Jaxen-1.1.6 and dom4j-1.6.1 worked for me.
