Hardy Ferentschik commented on HV-538:
--------------------------------------

Some observations from Gunnar:

* The logging around Contracts#assertNotNull() caused very many
invocations of String#format(), also if the asserted value actually
was not null, as MESSAGES.mustNotBeNull( "bla" ) was passed as
parameter. I've changed this by pushing the creation of the message
into the actual null case [1].
* The logging generally causes invocations of String#format() which I
think are are superfluous. More specifically format() is also invoked
if a given log message doesn't have any parameters. AFAICS the message
could directly be returned in that case. WDYT? I think we might create
a ticket against LOGTOOLS for this.
* When parsing mapping XML files, a new JAXBContext was created for
each input stream. I think we can re-use the same instance for several
input streams [2].
