Hi I've checked in modified code (see TUSCANY-3916) to deal with imports/includes. This doesn't use the file based approach but may be slightly different from the code you had originally. Can you give it a spin on the JVM/OS combination where you saw failures and see if this is any better. I haven't addressed the issue directly so it may or may not be an improvement just by chance.
