IllegalAccessError from TabFolder (more info) [message #442991]

TabFolder from SWT is producing a number of IllegalAccessError
exceptions.

Exception in thread "main" java.lang.IllegalAccessError:
org/eclipse/swt/widgets/Widget.checkBits(IIIIIII)I
        at org.eclipse.swt.widgets.TabFolder.checkS tyle(Unknown Source)
        at org.eclipse.swt.widgets.TabFolder.<init >(Unknown Source)

I removed the call to checkBits from TabFolder.checkStyle and ran the
app again. I get another IllegalAccessError:

Exception in thread "main" java.lang.IllegalAccessError:
org/eclipse/swt/widgets/Widget.isValidSubclass()Z
        at org.eclipse.swt.widgets.TabFolder.checkS ubclass(Unknown Source)
        at org.eclipse.swt.widgets.Widget.<init>(Unknown Source)
        at org.eclipse.swt.widgets.Control.<init>(Unknown Source)
        at org.eclipse.swt.widgets.TabFolder.<init >(Unknown Source)

If I remove that call, I get the same error from
TabItem.checkSubclass. If I remove that call, I get a
NullPointerException from TabFolder.createItem().

This very app ran fine on PocketPC 2002 WSDD 5.5 J9 2.0 jcl:foun. I'm
not sure what has changed.

Cheers,
Shaun

Of course this isn't true; I know what I changed. I moved to PocketPC
2003 WSDD 5.7.1 J9 2.2 jcl:ppro.

The Personal Profile (ppro) JCL from WSDD 5.7.1 includes an internal
subset of SWT. Any classes in this subset override classes provided
by the SWT in the classpath. SWT must be prepended to the
bootclasspath to override the internal copy. Here's an example:

"\Program Files\J9\PPRO10\bin\j9.exe" -jcl:ppro10
-Xbootclasspath/p:/share/java/SWT.jar
-cp /share/java/pocketmanager.jar pathway.pocketmanager.PocketManager
