[news.eclipse.platform] Class Loader failing from PreferenceNode.createP

[Michael Megliola <michael.megliola@xxxxxxxxx>]

Hi,

I am having trouble getting Eclipse to load a class by name.

I implemented a FieldEditorPreferencePage (called ArmPreferencePage).

Eclipse's class org.eclipse.jface.preference.PreferenceNode attempts
to load my class at runtime (within PreferenceNode.createObject()),
as part of the load sequence to display a PreferenceDialog that is
specific to my-plugin.

Eclipse fails with a ClassNotFoundException (@ PreferenceNode:161)

I exported the relevant package in my manifest.mf (below), I also
tried a variety of eclipse-buddy settings... although that seems like
it should not be needed for Eclipse to find my plug-in.

...any idea what I need to do to make my class visible to Eclipse
at runtime?

(thanks)
