I do not have any issues with what is contained within the any of the given content of the Xerces libraries. I do not have any issues with the fact that this version of Xerces will execute with any version of anyone's JRE.

I am referring to the following download site: > http://www.apache.org/dist/xml/xerces-j/ Did you try looking at the xercesImpl.jar MANIFEST.MF? It says... Created-By: 1.3.1 (IBM Corporation) Not sure about the rest below. However, I don't think the JDK used to compile the code should have much (any?) effect on performance at runtime. I suppose newer compilers might optimize the bytecode a little better. In any case, Xerces is compiled with a lowest-common-denominator JDK so that (I presume. Note I'm not a Xerces project team member, so this is my own $0.02)... 1. It can run in the earlier JDK's as well as the newer ones. Setting the "target" and "source" compile options are another way to do this, but that doesn't solve #2... 2. Newer API's aren't accidentally introduced.
