RegEx: look-behind-Assertions are buggy
Submitted by Anonymous on Tuesday, 7 September, 2004 - 00:49
When i search the word "foobar" for
foo(?=bar)
jEdit delivers "foo" as a result, which is right.

However, when I search for (?<=foo)bar, i get the following error Message, although i'm pretty sure my RegEx is OK so far.

gnu.regexp.REException: At position 1 in regular expression pattern:
quantifier (?*+{}) without preceding token
