Which VM are you using ?

I was using Sun JDK 1.4.1

Comment 5 Philipe Mulet

It feels then like a concurrency issue. When resolving multiple units at the 
same time, some required types can be requested simultaneously from different 
threads.

Comment 6 Philipe Mulet

2003-05-22 07:52:44 EDT

The imports list cannot contain nulls per construction, and the concurrency 
issue shouldn't occur based on the implementation which is protected by the 
model lock.

Steps to reproduce would be welcome.
