Thank you for reporting this problem! The error is probably some local problem, but its perfect that you have this problem, as it seems the error mapping in the Java binding is broken (it is probably untested as many errors like broken installation usually do not happen on the build server). Maybe you can find out via kdb what the error is and why this error code is not mapped.

I'll check whether this bug still exists
