> Key: BCEL-125
> URL: https://issues.apache.org/jira/browse/BCEL-125
> Project: Commons BCEL
> Issue Type: Bug
> Components: Main
> Affects Versions: 5.2
> Reporter: Nebojsa Grujic
> Assignee: Apache Commons Developers
> Priority: Blocker
> Fix For: 6.0
>
>
> In InstructionFinder class, line 229 size of the matched pattern is
> calculated as
> int lenExpr = (endExpr - startExpr) + 1;
> this is incorrect as endExpr is always given as one past the last index and
> this function causes the iterator being returned to always have one more
> instruction then requested. Also this can cause a crash if the pattern
> requested is at the end of a search list as index goes out of bounds.
> suggested fix (I have it working locally with no problems):
> int lenExpr = (endExpr - startExpr);
