Richard Eckart de Castilho commented on UIMA-2155:
--------------------------------------------------
It might also be an option to hardcode a test for this isse into the UIMA
framework which kicks in the first time a type system is parsed (or maybe the
first time an XML parser is created) failing with an explanatory exception.
After all, UIMA is bound not to be able to work properly with its own XML files
if this issue is present.

> Several people in our group that run Linux with the Sun JDK have run into
> problems that UIMA fails to parse descriptors unless Xerces 2.9.1 and Xalan
> 2.7.1. are on the classpath.
> It might be a good idea to add these two as standard dependencies to
> uimaj-core.
