(159/211) 3898 - Bracket matching not working on very large files with brackets very far apart

Not enough information to reproduce. Please attach a file as a test case.

I cannot attach the very large file ( 270 MB ) which illustrates the problem here. SF resets itself rather than allow that size of attachment.

Perhaps you can post it to a dropbox like site and attach a link to it?

Here is a dropbox link:

From my understanding, it seems that jEdit only matches brackets that are at most 10000 lines apart.

Is this mentioned anywhere in the documentation to jedit ? If not, where did you find this information ?

I don't think this is mentioned in the documentation, as I don't see it here:
http://www.jedit.org/users-guide/bracket-matching.html

I found that out by looking at the source code, and then confirming this fact with a few tests.

I'm an independent researcher, not actively involved in the development of jEdit, so hopefully one of the jEdit team can confirm this.

I think it would be helpful to note that bracket matching is bounded in the documentation.
