As far as I can see, something weird has happened to RE matches from about 4.3 Pre 13 onwards. I'm currently using 4.3 Pre 14 on Windows XP with JDK 1.6.0_02.
Suppose I create a document containing just "Hello", select "Regular Expression", and try some searches.
The following searches work: H.*o, H.*, .*o, e+
The following searches fail to match anything: .*, e*, l*
It looks like "*" isn't working properly in some circumstances.
I'm pretty sure this kind of thing used to work, notably things like (.*)

Also, ^ works but $ doesn't.

This looks a duplicate of the bug #1671312.

According to #1671312, the problem happens since jEdit 4.3pre9.

Yes, #1671312 looks to be in the same area. I guess that the * (possibly empty match) and the $ (which now seems to need \n as well) might make this the same issue. I hope the current situation is something that will be improved. The current interpretation of REs isn't very pleasant. Thanks!
