Description
Starting with FOP 2.4 the avalon framework is not used anymore.
Instead, a Configuration implementation has been added to the FOP: org.apache.fop.configuration.DefaultConfiguration
this new implementation uses the library "xercesImpl-2.11.0.jar" (not thread-safe ).
In multithreaded applications, I have the following exception:
