I just upgraded to pre10 (hoping to get a fix for the cpu-goes-to-100% problem), and suddenly C-`, which used to switch to the most-recently-visited buffer, no longer does anything. I'm pretty sure this was a core key-binding, as I think I learned it from the startup hints. Since I tend to switch between two buffers a lot, this was an easier (and less carpal-inducing) alternative to the RecentBufferSwitch plugin...

Hey all,

recently I've been getting a weird error message whenever I press '>' (i.e. shift and /)...

Everything works fine though, the angle bracket is ouputted, so the error is more of an annoyance then anything, but it is really annoying. Anybody have any ideas?

I'm getting null pointer exceptions. I tried upgrading to the latest jvm and latest jedit, but that didn't solve the problem. Here are some logs from before and after I upgraded.

(BTW I can't put this info in the bug tracking system because I'd have to create a sourceforge account. I already created a jedit.org account yesterday and had to wait until today to get login info emailed to me; don't want to create another account somewhere else and keep waiting.)

This is apparently the same bug as #1584436. http://www.jedit.org/CHANGES43.txt says it was fixed in 4.3pre10: "Scrolling up broken after content removing (#1584436) (Matthieu Casanova)". But it apparently wasn't fixed; I'm still getting the error, and somebody else reported it again as #1763932. The changelog for /jEdit/trunk/org/gjt/sp/jedit/textarea/TextArea.java says #1584436 was fixed in revision 8999. The diff to the previous version shows that all that was changed in this particular file was that a null pointer check and the corresponding error logging were deleted. They included the comment "FIXME - we need to reset the state of this window so that it has the right dimensions again." The offending line of code (both before and after the change), which is causing the null pointer exception, is attempting to dereference a pointer (named "point") which was returned by the function offsetToXY, but offsetToXY is returning null, apparently because screenLine is -1. Hopefully somebody who is familiar with the code can investigate what went wrong.

Jedit has a useful feature that if it crashes (or my system crashes), then the next time I start jedit, it will see my autosave files, tell me that it crashed, and offer to load the autosave files instead of the manually saved (old) versions.

When I first installed it, I had it assigned as the default program to handle txt files. However, I discovered that when I already had it running, and had some unsaved (but autosaved) files open, then if I tried to open a txt file from windows explorer, then a second instance of jedit would start, and tell me that it thought it had crashed (because it found autosave files), and offer to load the autosave files. This worried me because it apparently was unaware of (or unable to coordinate with) the instance of jedit which was already running, and I was afraid that in that case, one instance might clobber file changes made by the other instance. To be safe, I changed the default program for txt files to wordpad, to prevent a second instance of jedit from starting when I open txt files from windows explorer.

Why does jedit not recognize that the presence of autosave files is due to an already-running other instance of jedit rather than due to jedit having crashed?

In order to avoid the problem, is there a way I can set jedit as the default program for txt files but have it open those files in the already-running instance rather than open a new instance?

I rely on autosave. I ordinarily don't manually save my text files in jedit at all, until I need to open those files in other programs, since jedit automatically saves my changes. If jedit or my computer crashes, it's no problem, since when I restart jedit, it automatically finds the autosave files and offers to load them.

However, this safety feature recently failed catastrophically. I'd had jedit running for a couple weeks, and had made many changes to some files. Then my computer crashed, and when I restarted it and started jedit back up, I discovered that one of the autosave files, for a file to which which I had been making many changes every day, was empty! I lost a lot of irreplaceable data as a result.

I investigated, and found the problem. I had pasted some text which included an umlaut letter into the file, and jedit couldn't save it using the particular encoding which I had selected (windows-1251). As a result, it wrote a blank autosave file, and from then on, all of the text which I entered was stored only in memory, which was a disaster waiting to happen. I confirmed that this was the problem by creating a new file, pasting the offending letter, and trying to save it; I got this error:

I/O Error
c:\Users\Andrew\Documents\test.txt:
The following I/O operation could not be completed:
Cannot save: java.io.CharConversionException: Failed to encode the character
'ä' (U+E4) at column 1 in line 5 with the encoding "windows-1251".

It's true that that letter can't be encoded in that encoding. However, silently failing to autosave the file is a major fault of jedit. Furthermore, when I paste the offending letter into the file and then wait for the autosave, jedit writes "Input/output complete" in the status bar as usual, making me believe that the autosave was successful!

Automatically switching the autosave encoding to unicode (and notifying me of this fact) would be one solution to the problem. Another would be simply to display an error message alerting me to the fact that the autosave in my chosen encoding failed. But silently failing is absolutely the wrong thing to do.

A text editor's absolute highest priority, with no exceptions, is: never lose (or corrupt) the user's data. Sorry for ranting, but this is a bug which should not be allowed to remain.
It is present in both pre9 and pre10.
