It might seem obvious, but it's not. The bug is actually in the Java IDL
compiler.

eventtype is a keyword in CORBA 3. omniORB doesn't support that yet, but
it knows about the keywords, so if you try to create a type called
EventType, omniidl outputs a warning about a clash. To suppress the
warning, the definition of EventType is prefixed with an underscore.
That is a standard part of IDL that escapes identifiers clashing with
keywords.

See section 3.2.3.1 of the CORBA 2.6 or 3.0 spec.

Cheers,

Duncan.
