Description Jon Beatty 2009-02-06 13:47:25 EST

I am new to Eclipse and in my learning exercises I have run across a bug that I then found online at http://www.coderanch.com/t/106236/IDEs-Version-Control-other-tools/Cannot-remove-breakpoint-Eclipse.
It involves being unable to toggle a breakpoint on a line of code.  The code is an example from an online tutorial and I've included it below.  If I try to toggle a breakpoint on line 48 I get the breakpoint set.  If I then try to toggle it again to remove it, I get a second breakpoint.  I am able to disable it and to skip it but the only way I can remove it is to use the Run menu and remove all breakpoints.
I am using Eclipse 3.4.1.  Hopefully this is enough information to reproduce and resolve this issue.
Thanks.
Jon
