Try to debug the
input.getParameterAnnotations().length > 0
&& input.getParameterAnnotations()[0].length > 0
&& input.getParameterAnnotations()[0][0] instanceof JsonProperty)
By adding a breakpoint at the line input.getParameterAnnotations().length > 0, when debugging is started the breakpoint is rejected. But if we try to step into filter method and then step into Predicate#test method the debugger comes into this code block and everything like evaluations works.
This works as expected by adding the line breakpoint as mentioned above in Eclipse.
