Umbrella of fixes in parameter names in operations:

1/ JConsole represents the operation's return value for arrays with the name
   of the java class followed by "[]". For example, "java.lang.String[]"
   instead of "[Ljava.lang.String;"

   The same logic should be applied to the operation's parameter names.

2/ Primitive type arrays are represented with the name of the primitive type
   followed by "[]". For example, "long[]" instead of "[J".

   The same logic should be applied to the operation's parameter names.

3/ The type "java.lang.Boolean" in a parameter should have a default value
   of "true" instead of the java classname.
