StringIndexOutOfBoundsException in org.jruby.util.JavaNameMangler
-----------------------------------------------------------------
Key: JRUBY-4681
URL: http://jira.codehaus.org/browse/JRUBY-4681
Project: JRuby
Issue Type: Bug
Components: Java Integration
Affects Versions: JRuby 1.4
Environment: WinXP, J2SE 1.6
Reporter: Marek Sajna
Priority: Minor
I'm getting StringIndexOutOfBoundsException: -3 while running Rails 2.3.2, but
I was unable to track down when, it happens randomly while request is handled
by Mongrel.
I guess that line 39 of org.jruby.util.JavaNameMangler contains typo, or is "6"
as beginIndex appropriate? Looks like there's "!" at index 3 of the String and
that causes the error. I'm unable think of another explanation, not even to
find something on the issue on google.
{code:Java}
38: if(filename.indexOf("!") != -1) {
39: String before = filename.substring(6, filename.indexOf("!"));
{code}
