Heiko Selber commented on XALANJ-2374:
--------------------------------------

The problem occurred for me when I upgraded from java 1.7 to 1.8 (1.8.0_102-b14) on Debian 8.6.
The only way to fix it was downloading the sources and applying the fix described here.
We depend heavily on xalan, so a bugfix release would be great.
