Please handle gracefully the IOOBE, or check that line number < # of lines in the document.

Hi,
the "PMD" plugin is no longer maintained.
Please consider using the "EasyPMD" plugin instead.
Thx.

This issue should be reinvestigated, as it has nothing to do with PMD (in my case I was editing a pom.xml file) & already has 19 duplicates.

The cause is as said earlier in the defect. Text API caller has to either ensure the line number is valid (i.e. read-lock the document, check the # of lines, perform operation) or face IOOBE and handle it.

Exception reporter sometimes misreports related exceptions, although the stacktrace is different - attaches to a wrong group of reports. Your issue (report #766366) should be created for maven support (see your own stacktrace).

Please do not change components unless you investigate the reported issue in detail.

Sorry for having changed this issue, but I did read through the comments. And since the stack trace in the description matched mine exactly, I thought this was the appropriate issue to report my problem. All the more since there were already 19 duplicates.
As a mere user, I'm unaware that NetBeans has a Text API which is called by all the other components. And that those components have to call the Text API in a correct way to avoid IOOBEs like this. Also, if NetBeans gives me an error in the Text API, I don't see how I'd be able to know whether it's an error in the Text API itself or in the component that uses it. Anyway, thanks for clarifying, I'll remember this for the future :) And thanks for creating the new issue.
