after application start the msg box is displayed asking if unlock index \[CtagsInterface one\].
if no is selected then application stucks.
if yes then sometimes it success but i think then index is cleared and the source trees have to be defined again in CtagsInterface plugin \[but this is to be verified\].

there is definitely bug in Lucene as it is unable to share Ctags indexes between instances.

i'm using jEdit 4.5pre1 daily build from 2011.02.15.
CtagsInterface 2.1
lucene-core-3.0.2.jar
lucene-highlighter-3.0.2.jar
lucene-memory-3.0.2.jar
LucenePlugin 2.6
