xstream before 1.4 does not support Java 7. See :
and current change log:
This is causing me problems as I cannot read files from within a plugin that are created with xstream 1.4.2 since they are incompatible with the current 1.3.1 version. And reverting the program creating the file to 1.3.1 is not possible as this will lose Java 7 support.
