[Bluej-discuss] Slow Directory Navigation

[Chris Share]

I'm using JDK 1.6.0_02.

I'm also using the Java Standard Edition 6, Version 1.6.0_03-b05 runtime.

The folders in question don't contain large zip files, large numbers of files or network drive links--only smallish BlueJ projects.

BTW, I've found that another Java program I use (JabRef) is also showing the same problem.

Also, I've found that if I revert to using JDK 1.6.0 the problem goes away.

Looks like it's a problem with the JDK.

Cheers,

Chris

 Hi Chris,


Can you advise on which Java version you are using? 

There have been a number of Java bugs involving JFileChooser dialogs that are very slow under certain circumstances. One bug involved large zip files in the directory being browsed, others when network drives are present, or the directories are large. 


The large zip file bug is listed as fixed for Java 7, the others are still open.

jEdit is not probably the best comparator as it doesn't use Swing JFileChooser dialogs (as far as I know), they created their own from scratch.


Do the folders in question contains large zip files, large numbers of files or network drive links?


Is anyone else getting the same problems? If you have more than one Java JDK version on your system it would be interesting to see if the behaviour is present on more than one version.

Hi,


For some reason, directory navigation in BlueJ has suddenly become very slow. If I try to open a file, there's a delay of roughly 10 seconds before the file dialog opens. The delay is also happening when I navigate to a new directory.


It seems that this problem is only happening in BlueJ. It's definitely not happeing in any other Java apps like jEdit.


I'm running BlueJ 2.2.0 on Windows XP.


Any idea what's going on?


Cheers,


Chris
