You can hide this by adding the following line to logging.properties:
log4j.logger.com.itko.lisa.vse.stateful.common.datahandler.XMLPayloadParserDataProtocolHandler=FATAL
> ERROR System.err - [Fatal Error] :1:1: Content is not allowed in prolog.
This one is more problematic, as the XML library we're using is writing this directly to Standard Error. There are some ways to disable this in code, but I'm not aware of any system properties you can set.
However, if it's happening often enough that it needs to be suppressed then maybe there's a bigger problem. Why is the XML Data Parser DPH being run against requests bodies that are probably not XML?
