java.lang.LinkageError when viewing Beans Graph in Eclipse 3.4.2

[mbabauer]

When I try to view the Beans Graph for one of my Spring Context files, I get the following error:

java.lang.LinkageError: loader constraint violation: when resolving overridden method "org.springframework.ide.eclipse.beans.ui.graph.pa rts.GraphPart.createFigure()Lorg/eclipse/draw2d/IFigure;" the class loader (instance of org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader) of the current class, org/springframework/ide/eclipse/beans/ui/graph/parts/GraphPart, and its superclass loader (instance of org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader), have different Class objects for the type org/eclipse/draw2d/IFigure used in the signature

Google hasn't been much help.

I found that some other feature was making osgi create an old draw2d jar even though the newer draw2d plugin seemed to be the only one available. In my case uninstalled both inCode and the Memory Analyser and Spring bean graphs are working again.

Why is the Spring feature not dependent on the correct draw2d plugin?

All,

what version of Spring IDE are you using? The very recent 2.2.x and greater versions don't support Eclipse 3.4.2 any more.

What is the reason that you stick on this pretty old version of Eclipse?

Cheers,

Christian

Sorry, I should have pointed out that this was still occurring in Eclipse 3.5.2

SpringIDE is 2.3.0.200912170948-RELEASE
