Hi,
We have service-mix 4.4.2 running with Java 1.6 on a red hat machine.
Sometimes, when we start up a module we get the following error. On our second
attempt to start the module the error does not happen.
Earlier, I thought that this error might occur due to conflicting versions of
xercerImpl jar, however, our server has
-Djava.endorsed.dirs=/usr/local/apache-servicemix/lib/endorsed and the endorsed
directory contains
xercesImpl-2.11.0.jar and xml-apis-2.11.0-20110622.jar, so it should force
servicemix to use version 2.11.
Any thoughts on what might cause this error.
