> We got a NullPointerException trying to start a Derby database in embedded mode; the
stacktrace indicated it happened in org.apache.derby.impl.io.DirFile.deleteAll(); that method
got called from org.apache.derby.impl.io.BaseStorageFactory.createTempDir().
> After investigating, it appears that the deleteAll() method calls "super.list()", which
according to the java.io.File specifications, can return null. But the deleteAll() method
doesn't handle that case gracefully.
