#1504 [java] InvalidSlf4jMessageFormat: False positive with placeholder and exception

[Andreas Dangel]

See: https://github.com/pmd/pmd/pull/73#issuecomment-231346287

I'm not sure if this is a correct place to report, but with this change we are getting a lot of false positive
when message contains just one placeholder and we are passing parameter for that placeholder and
exception itself to be logged (which is a valid scenario). So for this statement:

LOG.warn("My message with some placeholder here: {}", valueForPlaceholder, ex);

I'm getting:

PMD Failure: <class name and line here> Rule:InvalidSlf4jMessageFormat Priority:5 Too many arguments, expected 1 argument but have 2.

That's actually a duplicate of [#1500]
