Yes, not just confusing but incorrect, the updated static field will affect
what is tested so you are dependent on the order of test method execution. Make
the field final and use the convention for static field names, and drop the
assignment for the insertArgument calls.
118 @Test
119 public void testInsertArgumentsPosZero() {
120 countTest();
121 try {
122 methodHandle = MethodHandles.insertArguments(methodHandle, 0,
"First");
123 methodHandle = MethodHandles.insertArguments(methodHandle, 1,
"First", new Object());
124 Assert.fail("ClassCastException not thrown");
125 }
126 catch(ClassCastException cce) {
127 }
128 }
You can split this out into multiple try/catch, one for each
MethodHandles.insertArguments call so the assertion directly captures the
failure point, otherwise declare the exception in the @Test.
