Callback before a given method is invoked.
Params:
method – the method being invoked
args – the arguments to the method
target – the target of the method invocation. May be null.
Throws:
Throwable – if this object wishes to abort the call.
Any exception thrown will be returned to the caller if it's
allowed by the method signature. Otherwise the exception
will be wrapped as a runtime exception./**
