Re: [ jEdit-devel ] ArrayIndexOutOfBounds in Buffer.getText()

[Slava P. <sl...@je...>]

This is very strange. The code in question is as follows:

int lastLine = Math.min(9,getLineCount() - 1);
parseBufferLocalProperties(getText(0,getLineEndOffset(lastLine) - 1));

Buffer.getLineEndOffset() should _never_ return an offset past the end
of the buffer. The file size reported by the JVM is irrelevant here.

Does this occur randomly, or only with certain files? With files where
this occur, are there other problems as well, or is it just this code
chunk that breaks?
