Christofer Dutz commented on PLC4X-312:
---------------------------------------
Hi [~kdxq],
thanks for finding and reporting this ... I was able to reproduce the problem
and am currently running the testsuite to ensure this didn't change anything
else. I am however a bit puzzled that this wasn't spotted any earlier :-/
Regarding the release ... we're currently tying up some loose ends and am
expecting to start the release process soon (Happy you found this bug now so
you won't have to wait too long for the fix to be released)
