Knut Anders Hatlen reopened DERBY-5615:
---------------------------------------
The fix for this issue seems to cause problems for the tests on Windows.
DatabaseClassLoadingTest fails to delete dclt.jar when it's done. Reopening the
issue.
I've found out how to fix it, but I don't understand why it's failing in the
first place.
Originally, in CPFile, the getInputStream() method and the getURL() method were
almost identical, only that the former used ClassLoader.getResourceAsStream()
and ClassLoader.getSystemResourceAsStream() whereas the latter used
ClassLoader.getResource() and ClassLoader.getSystemResource().
To minimize the duplication, the 1b patch rewrote getInputStream() so that it
essentially just returned getURL().openStream(), plus some error checking.
If I reintroduce the code duplication, the test runs cleanly on Windows again.
So there must be something different with that approach, I just haven't figured
out what.
