------------------------------------------------------------------------
You're right, I was just assuming it was a concurrency issue as I encountered
it in the JMeter plan running 10 simultaneous threads. Didn't look into the
issue yet.
You can easily reproduce it by invoking this request;
http://localhost:3737/rest/users?filter=sdfxdvd
It is under test by UserAdminRESTTest, but the test does not test this specific
method very thoroughly, will add that. See if I can break up some code and
implement that part as unit test instead.
There is DEBUG logging here indeed, but unfortunately we have no guarded
logging in the OSGi LogService as you mentioned before. I will add some check
to enable/disable this at compile time, as the information printed there is
very useful during development.
