Marshall Schor commented on UIMA-2155:
--------------------------------------
Thanks for your persistence in tracking this down. Do you have an example
descriptor which fails to parse?
The reason I ask is that I would like to be able to reproduce this error and
confirm 2.6 doesn't work. I looked at one Java I'm running (IBM 1.6, SR9 FP2)
and ran the command "java org.apache.xalan.xslt.EnvironmentCheck" which said
the xml related things were coming from the Java boot class path, in the jar
"xml.jar", I looked into that jar, and found a /licenses/notices.txt which says
in part that it includes Apache Xalan-Java v2.6.
I'm not sure this information is reliable/definitive, and would like a better
way to identify the version. But if this is true, then it would seem to
indicate the problem is elsewhere, because I don't see a problem running with
the native version of Xalan that comes with this Java.
So a small example which "fails" would be very useful in pinning this down.

> Several people in our group that run Linux with the Sun JDK have run into
