- temporary integrated the transferURL servlet as static class instead as a class that is called using reflection to investigate the OOM problems in that class
- fixes for numerous other problems - removed dead code - resdesign of the strings-method, which produces now less memory overhead and may help to prevent OOMs - another fix for the deadlock problem in SplitTable git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@6373 6c8d7289-2bf4-0310-a012-ef5d649a1542pull/1/head
