Andreas Veithen commented on AXIS-2863:
---------------------------------------
I found a version of the Oracle parser, but I haven't been able to reproduce
the issue. I also have no theory to explain how the issue could occur.
Nevertheless, I did a couple of changes that should solve the issue or at least
reduce the impact of the issue. Can you download the 1.4.1-SNAPSHOT version
from [1] and redo your test?
