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?
