Hi
SyncopeClient.getService appears to be a construction call and as such
it is not expected to be thread-safe.
Though I guess it can be made thread-safe if preferred but that would
likely imply passing the user name and password to getService() method
too to avoid having cached CXF client factory beans.
The actual CXF proxies (ResourceService, etc) can be made thread safe
too by having a thread safe flag set on them:

Hi all,
we have some problem with multiple cxf calls to Syncope core, seems that
some concurrent problem breaks syncope client calls.
Here a part of the stack trace error:

We’ve done a unit test to reproduce the problem, you can find it here
(not the real unit test but an adaptable example):

Hope this will help to have major details.
Kind regards.
