I'm not at all sure about the declaration you're showing (maybe somebody else recognizes this crazy notation) but a variable with a "synthetic" attribute means a variable introduced by the compiler that doesn't appear in the actual code. Examples include a static variable to hold a Class object if you've used the "Integer.class" notation, and the member variable in a non-static inner class that holds a reference to the enclosing class. Besides the fact that they are inserted by the compiler, synthetic variables aren't special in any way. Debuggers are supposed to take the synthetic attribute as a hint that they shouldn't display the variable.
