Hi Daniel,
* Or maybe rephrased: if reflecting an UNO object, does one need to
use an instance of "com.sun.star.reflection.CoreReflection" from
the same context as the reflected UNO object?
No, you need not use the same component context, but it may be more
performant to choose one within your process. Please use the singleton
entry
"com.sun.star.reflection.theCoreReflection"
for the sole reason that it internally caches created IdlClass objects.
When will that object be registered? Is there anything I could do that
it gets registered and available at bootstrap time?
What follows is a small Java program that shows that "theServiceManager"
is registred with the context, but "theCoreReflection" object is not yet.
In your example you bootstrap a new fresh Java UNO env. I assume that
the singleton is not registered in this env but when you use the native
bootstrap mechanism or use the context from an office this singleton
should be registered.
This can maybe considered as bug and you can submit one or an request
for enhancement if you want.
