FooPlugin.getDefault() returns null from code running inside the Foo plug-in [message #292715]

I create in Eclipse 3.1 a plug-in called "Foo", and its AbstractUIPlugin class, called FooPlugin,
contains (as always) a method getDefault() to return the singleton instance of FooPlugin.

Somewhere else in the code of the Foo plug-in I call FooPlugin.getDefault() -- for example, to be
able to write to the log -- but the return value is null. Every time.

In most of my plug-ins this has never happened, not once. Why would it be happening in the Foo
plug-in? I.e., where should I look for the difference that is causing this?

thanks,
Paul

Perhaps FooPlugin has not been started?
Is the code calling FooPlugin.getDefault() within FooPlugin or is it from
some other plugin?

Check to see that the MANIFEST.MF has the following:

Eclipse-AutoStart: true

Without it, the FooPlugin won't be activated on the first reference to
any class in Foo.

Weird. We do have that line, and always have. As far as I can tell, the problem is some environmenmt
thing -- do fresh Eclipse 3.2M2 install, point at a suitable JRE (some of our code does not like
Java 1.5, alas), fresh checkout of all projects, and no problems.
