That explains why the compilation fails. It does not explain why the 
self-hosting scenario fails when I have the plug-in imported into my 
workspace.

I'm trying to understand if the two problems (the compiler not handling 
embedded jars and the runtime not handling the imported plug-in) should 
be considered bugs in Eclipse or if the Subclipse team has misunderstood 
something. Also, for participation in Europa, 
http://wiki.eclipse.org/index.php?title=Europa_Simultaneous_Release, one 
of the "Should do" items is " "Projects should have jar'ed plug-ins 
because this is good Eclipse citizenship.". Would it be fair say that 
one of the requirements on Eclipse in that case must be that they are 
handled properly? At present, that doesn't seem to be the case.

Are there any plans to make the compiler handle embedded jars before the 
3.3 final release? If not, I suggest adding "The exception is when the 
plug-ins contain embedded jars" to the said "Should do" item.
