In Eclipse 3.4, this method is no longer called from Main UI thread (as it
used to be in < 3.3)but instead from a worker thread..is this a bug? if
not then the javadocs need to be updated..

It's not a bug, just a slight change in the startup sequence.

AFAIK the javadoc for
org.osgi.framework.BundleActivator.start(BundleContext) makes no mention
of it starting on the UI thread.

Even the implementation in AbstractUIPlugin posts its refresh action to
the asyncExec(*).

It's just something to be careful of, you can use a WorkbenchJob or
UIJob to post any UI initialization until later in the startup sequence.
