#160 Parser issue with large files => ArrayIndexOutOfBoundsExce

[Dominik Ertl]

Larger Files (like the one I use here with about 3500 lines of code) seem to have problems with the C#codeparser:

During typing of code (like System.Console.xyz), e.g. the code completion is very slow.
It seems that the CodeCompletion-Job gets no resources, as other jobs in the background (C#codeparser) require too much processor time. (Maybe typing with usage of backspace and re-typing is needed)
Finally, it leads to an ArrayIndexOutOfBoundsException caused by CSharpCodeParser.checkForCommentedOut.

Any ideas?

I tried using 'System' and then pressing the '.' and also tried using Ctrl+Space after 'System.' but I cannot reproduce the AIOOBE on Eclipse 3.2.2.

It is, however, definitely very slow. :p After some simple tests, it seems that parseDocument() is taking about 1.4 to 1.5 seconds.

The 'Outline' view also keeps refreshing, which is quite annoying.
