There's a specific bug in the bundled XML libraries in 1.5 that is
not present in the same libraries in 1.4. This is what I need to
work around. It is not a question of source level compatibility. I
need to *run* Ant with the Java 1.4 VM. It is not enough to use java
1.5 but tell it to enforce 1.4 source levels.
Could you elaborate on this bug?
I ask because the 1.4 XML handling facilities were from Crimson,
whereas the Xerces and Xalan products from Apache took that role in
1.5.
