local lambda and resolveRawArguments returns previous defined local variable class

[mickare]

Java version: Oracle 1.8.0_45

Test-Code:

  @Test
  public void testLambdaFunctionVariableInMethod() {

    final AtomicInteger a = new AtomicInteger(0);
    Function<String, Integer> func = (s) -> {
      a.incrementAndGet();
      return s.hashCode();
    };

    assertArrayEquals(new Class<?>[] {String.class, Integer.class}, TypeResolver.resolveRawArguments(Function.class, func.getClass()));

  }

Fails with:
arrays first differed at element [0]; expected:<class java.lang.String> but was:<class java.util.concurrent.atomic.AtomicInteger>

---

The Test-Code using a final AtomicInteger in the test object is successfull:

  private final AtomicInteger b = new AtomicInteger(0);

  @Test
  public void testLambdaFunctionVariableInObject() {

    Function<String, Integer> func = (s) -> {
      b.incrementAndGet();
      return s.hashCode();
    };

    assertArrayEquals(new Class<?>[] {String.class, Integer.class}, TypeResolver.resolveRawArguments(Function.class, func.getClass()));

  }
