Build x73-idl-ospl-dds failed

I have installed an evaluation-version of VortexOpenSplice (6.6.2p1) from PrismTech. If I try execute task "osplIdlppJava" - following errors are thrown:

:data-types:x73-idl-ospl-dds:osplIdlppJava FAILED

It seams that type "wstring" is unkown in VortexOpenSplice and I can't see declarators "alarm_limit_type" and "alarm_limit_thresold" in file "x73-idl/src/main/idl/ice.idl"?

Can you help me please?
