If there is a return value(Boolean or anything), this problem is not
there.

All the specific exceptions will be correctly passed. This seems an issue
with Axis2. See the other thread where Chamila explained the issue as
follows,
"The issue with custom exceptions not being returned was that in the stub
when recreating the exception, in the returned AxisFault, 'detail' field is
being set to null."
So the details field does not become null when there is a non 'void' return
type. So any custom exception can be catched.

No. But this will be a fair workaround, since we are planning to migrate
AS/CC services to Rest services ASAP.
Thanks.
