[mdr-users] Different instances of NBMDRepositoryImpl are not independant from each other - Feature or Bug?

Hi,

when I have two instances of NBMDRepositoryImpl running within the same VM
they seem to influence each other:

First:

_args = new HashMap();
_args.put("storage",
"org.netbeans.mdr.persistence.memoryimpl.StorageFactoryImpl");
_args.put("STORAGE_ID", "first");
MDRepository repository1 = new NBMDRepositoryImpl(_args));

Second:

_args = new HashMap();
_args.put("storage",
"org.netbeans.mdr.persistence.memoryimpl.StorageFactoryImpl");
_args.put("STORAGE_ID", "second");
MDRepository repository2 = new NBMDRepositoryImpl(_args));

Then:

repository1.createExtent("foo");
repository2.createExtent("bar");

Results in:

It seems that this is also true for two MDRepositories with different
storage types. Maybe the problem is located deeper?
Is it a feature or a bug?
It would be kind of maddening if two ore more MDRepositories in one VM were
not possible to run ;)
