Description Svata Dedic 2000-09-20 14:58:42 UTC 
A test that creates a Java source from a template, then closes and removes the
file suffers from the following exception:

Comment 1 Svata Dedic 2000-09-20 15:04:59 UTC 
There's a race condition between a test whether the document is loaded and
acquiring the document. If another thread closes the document in the meantime
(about 6 lines of code between the test and getDocument()), NPE is thrown.
Comment 2 Quality Engineering 2003-07-01 13:19:02 UTC 
Resolved for 3.4.x or earlier, no new info since then -> closing.
