Quickly test/preview didn't work

[mkornatzki]

Hi,

the quickly text / preview button in the toolbar didn't work.

The following happened even if i only have a jframe.

In the EclipseConsoleLog i get the following:
Exception in thread "AWT-EventQueue-0" java.lang.IllegalStateException: Buffers have not been created

currently i use the latest version of swingdesigner (7.1.0.200909290340).

Never seen anything like that before, but it looks like a bug in Swing...

that means it is only a problem on my computer?
i didn't change the java-version (java 1.6.0_10) for nearly 3 weeks i give a workshop with this computer and the eclipse.
i only make updates for eclipse and the eclipse-plugins.
i only want to preview a simple jframe that was never before a problem?

i will test it with another installation.

michael

I don't know. We tried it on 5 different computers here and it worked fine. We have not had any similar reports from anyone else either.

This is a Sun/Java bug, but I have no idea how, where or why it is triggered (your stack trace did not include any mention of our code).

Hello,

now i can give more information about my problem. i have found the problem or better a configuration where the problem occurs.

i take a clean eclipse 3.5 with actual updates and the stable SwingDesigner 7.2
Make a Testproject with a TestFrame extended from JFrame.
click Preview and then the following happens:

Multiple scenarios tested:
* Start Eclipse with Java 1.5.0.16
Make a Project in Java 1.5.0.16
Preview works
* Start Eclipse with Java 1.5.0.16
Make a Project in Java 1.6.0.16
Preview works

* Start Eclipse with Java 1.6.0.16
Make a Project in Java 1.5.0.16
Preview crashs
* Start Eclipse with Java 1.6.0.16
Make a Project in Java 1.6.0.16
Preview crashs

I also make a test with the SwingDesigner 6.9.3 and there is no problem when i start the eclipse with java 6.

Do you make a test also with Java 6 as starting Java-Version for Eclipse?

regards, michael

We tried Java 1.6.0.16 and did not have any problems.

Maybe try downloading it again from the Sun Java site?

Thank you for your endurance.

after multiple tests and reading the links you posted i found a solution (not a good one but...)
In one posting i read that the problem starts with Java 1.6.0_07, so i test Java 1.6.0_06 and the error didn't occur.

It's very starnge because i had used eclipse and swingdesigner with a higher java version a long time (maybe a windows update make the problem?).

I will run my eclipse now under Java 1.6.0_06.

thanks,
michael

With so many combinations of OS updates, drivers, and JDk versions out there, who knows what the cause might be.

We tried Java 1.6.0_06 on several different machines, and did not have a problem, but we have seen problems with other JDK releases in the past.
