What JDK version are you using to run Eclipse? (java -version)
–java version “1.4.1_01”
–Java(TM) 2 Runtime Environment, Standard Edition
–(build 1.4.1_01-69.1)
–Java HotSpot(TM) Client VM (build 1.4.1_01-24, mixed mode)

What JDK version are you using to launch your application server?
–same
What steps did you take that resulted in the issue?
–see below
What application server are you using?
–Tomcat 5.0.9 (not in use when the problem occurs)

The problem:
After installing MyEclipse 2.6.1, I have the following problem while debugging a stand-alone Java application.
When paused in the debugger, I right-click a field and choose “inspect”. The “inspect” window does not open. The following stack trace is written to the log. This also occurs if I choose “watch” from the same contecxtual menu.

If I uninstall MyEclipse, the problem disappears and the “inspect” command works.
(By the way, I’m very impressed with MyEclipse so far.)

Halverg,

First, thank you for posting all the information we requested in our guidelines. I believe your problem is caused by using JDK 1.4.1 to launch Eclipse. Neither Eclipse nor MyEclipse is tested on JDK 1.4.1 on the Mac and there are known issues with Eclipse in this configuration. To correct the issue, please use JDK 1.3.1 to launch Eclipse. You may use JDK 1.4.1 to launch your servers without a problem, just not Eclipse itself.

–Scott
