All I can say is that this has always occurred while placing controls on the form or when attempting to change properties of a control on the form and, so far, always in the Design view

At various points, the cursor moves a bit and turns into an hourglass and never returns. When I bring up the task manager, it says Not Responding. I’ve waited a long, long time and it nevers comes back and I have to kill it with Task Manager.

I have the status screen that MyEclipse print upon being closed by the Task Manager if that will help. I don’t see any means to attached it.

What OS are you working on? I’ll get this checked right away.

Doug,
Could you go to MyEclipse > Installation Summary > Installation Details and paste that information here for me?

Also, can you give me some background info on the project and components you are using? For Example… Java 5 project, custom components, Swing components, SwingX components, etc?

Also any details about the hanging… happens immediately, every time… random, etc?

[DougMH]

I amy simply working through the “Matisse4MyEclipse (M4M) Tutorial

Swing Components:
Label
TextField
Panel
RadioGroup
RadioButton

AWT Components:
None

Platform: Windows XP Pro
Dell Optiplex GX745
core 2 duo
2.13GHz 1.99GB Ram

JDK: Java 6

Eventually, it has happened everytime.

NOTE: I downloaded the All-in-one 6.5M1. My company does not allow me to connect to search for software updates so I downloaded and installed: MyEclipse_6.5M1_UpdateSite.zip to add the Matisse/Swing capability

Doug, is there an approximate time that it takes before the lockup occurs or is it totally random? Sometimes 2mins, sometimes 2hrs?

[DougMH]

I can say this for certain. It always happens when I’m making some change to the properties. In the latest installment, I added a JPanel to the bottom of my form. Then I put a label on the JPanel. I went to blank out the default text (jLabel1), the “text” field would not focus and after about 2 or 3 seconds, I got the hourglass and after that nothing. Control is lost forever until I force the program to close and start it over.

[Riyad Kalla]

That is really frustrating and the worst part is it’s not giving us any symptoms or triggers to diagnose to pin-point it.

If you have the time, what I’d like you to try is to actually install the Sun JRE 1.5.0_11 (specifically the _11 version). There was a change in _12 and beyond that related to the Swing rendering system that *has* caused lockups for us with Matisse when run inside Parallels on Mac or other VM software, but we haven’t reproduced it stand-alone machines… however, if backing up to _11 fixes the issue for you, that will be a very important data point for us to know.

[DougMH]

I can do that. I’m currently running…

c:\WINDOWS\system32>java -version
java version “1.6.0_06”
Java(TM) SE Runtime Environment (build 1.6.0_06-b02)
Java HotSpot(TM) Client VM (build 10.0-b22, mixed mode, sharing)

… out of c:\windows\system32.

It seems a shame to have to drop back several iterations of the JRE… especially when I’m running 1.6 of the JDK. I know when I try to run stuff I’ve developed in 1.6 that I get an immediate exception when I try to run it under an old 1.4 JRE. Will not the same situation exist if I try to run 1.6 JDK developed apps under 1.5 JRE?

[DougMH]

I haven’t had a chace to to revert to 1.5_11 yet, but I think I can give you a situation where the program will hang.

I was adding icons to buttons, then because I don’t like the way that property is added (I’ll do another post on that specifically), I removed them all. During the removal process, it hung. I think if you create a button and continually add and then delete an icon, at some point the program will hang.

Oh, I just want you to add the 1.5.0_11 JRE to your system, I believe by default your system will still keep the 1.6 JRE registered as the default. You don’t have to remove it.

How long did it take? I just tried adding/removing icons to the M4MContactManagerExample project from EoD about 12 times… so far so good…
