Hello,

I have run into quite a painful issue with the MyEclipse Matisse editor.

From time to time, while attempting to edit certain JPanel-based form fields in the properties form view in the Matisse perspective, Eclipse hangs and I am forced to terminate the process.

If the JPanel form has been modified since it was opened in the Matisse perspective, on the next starup Eclipse goes into a full refresh recovery mode which in my case can take up to 20-30 minutes due to the large codebase I am working with.

Here is the stack trace:

On startup, Eclipse prints the following to the log:

BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=en_CA

!ENTRY org.eclipse.core.resources 2 10035 2008-09-08 01:15:49.364
!MESSAGE The workspace exited with unsaved changes in the previous session; refreshing workspace to recover changes.

20 minutes later I can continue my work. 🙁

I’m running MyEclipse 7 with Eclipse 3.4 on Windows Vista.

Can someone help?

Thanks

Can you go to MyEclipse > Installation Summary > Installation Details and paste the information here for me.

You started facing this issue after upgrading to MyEclipse 7.0M1?

tarantula,
It seems like you are using JFK 1.6. Can you switch to 1.5.0_11 and test matisse again. I think 1.6 is causing the problem here.

You will have to make the change in the eclipse.ini file or the MyEclipse shortcut. Point the -vm argument to point to JDK 1.5.
