Dag H. Wanvik commented on DERBY-4179:
--------------------------------------
Ok, the test framework starts bootLock in a subdirectory (different from the
cwd when the test is started), so the forked
process (bootLock1), will have the wrong CLASSPATH: since it consists of
relative paths to the jars, i.e. relative to the directory in which the test is
*started*, not relative to the created subdirectory, the forked subprocess will
fail, leaving the way open for bootLock to open wombat without seeing it
already opened/locked. No dual boot is really happening :)
As far as I can see, this is a test bug, not a product bug, at least in the
incarnation I am seeing.
