Detect ignored exception which is not logged

[KengoTODA]

Sometimes we ignore exception without intention. For instance,

before():
try {
  someMethod();
} finally {
  after();
}

If both of someMethod() and after() throws Exception, we will lose exception which is thrown by someMethod(). It will make debug/maintenance difficult.

I could not find common name to explain this problem. Maybe 'lost exception' is good word. I will use this.

BTW, currently test-driven-detectors4findbugs does not support Detector2 interface.
We have to solve this problem at first, because we will use CFGDetector to analyze data flow.

My patch has been merged, now test-driven-detectors4findbugs supports Detector2 interface.
I think we can wait new release to use.
