Are you running the tests in parallel? IIRC, that kind of thing occurs
because one process is in the process of overwriting the .class files
required by another (e.g where tests share source files).

(I've just started a bootcheck at -j1 on my machine -- I'll let you know
if the problem occurs there.)
