@jbescos I assume this is better performance-wise since the try-catch clause is slow in general. On the other hand, this code tests all the methods and iterates through them. I expect only a very limited number of methods and hence a speedup, but...have you tried to test the performance a bit with this (I do not mean a Jersey test of any kind, more a loop of numerous operations checking for the "value")? The code around the parameter class is utilized quite often in the runtime and can have a measurable impact.

I am running it, and I am surprised that the #getMethod performs only 25% slower when there are only 3 methods. When there are many methods (for example when you iterate the methods in String class), in the worst scenario, iterating all the methods is around 300% slower.

Till this point, it looks better to use #getMethod.

However, if exception is thrown because there is no such method, #getMethod performs 1200% slower than iterating 3 methods, and 200% slower iterating the methods of a String.
