[Pljava-dev] Exception in read/write text files

I believe you have to use the untrusted java (javaU) -- I can't access
the pljava wiki at tada[1] for some reason at the moment, but I
believe there are instructions there for how to add a function that
uses the untrsted java language extension rather than a normal trusted
one (untrusted allows access to the filesystem).
