I propose to remove unnecessary condition in LocalVariableTableParameterNameDiscoverer.

Thanks for the PR.

Although org.springframework.asm.ClassReader.readStream(InputStream, boolean) would eventually thrown an IOException for a null InputStream, we shouldn't rely on that.

In addition, aborting immediately when the class file is known not to exist is an optimization of the code in question.

In light of that, I am closing this PR.
