For my 0.4 Release, I've been trying to find a bug to work on that could provide me with a good introduction to the Eclipse system. I came across Bug 142301, which states that there is a fix required for one of the wizards. The fix must not allow the user to enter an invalid filename (ie. something with *&^%$ characters). If the user attempts to enter an invalid filename, the Next and Finish buttons are to be disabled and a message needs to appear to notify the user.
I feel like this is a good bug to start off with, and thus I will be working on it for my 0.4 (and perhaps in future releases as well depending on how successful I am).
One thing I find disheartening is that there seems to be no IRC channel for Eclipse developers. I'm worried that I won't be able to receive the same kind of support from experienced developers that I enjoyed with Mozilla. However, Jordan has pointed me towards the Eclipse newsgroups, which apparently have plenty information. I hope so because I have no clue how to re-create this bug or where I can find the relevant code.
