Synthetic Enum Method Handling

[Adam Lewis]

Hi Guy,

I have a failing test here. It should be pretty self explanatory:

package org.deuce.test.basic;

import junit.framework.TestCase;
import org.deuce.Atomic;

/**
* Enum types have several synthetic methods generated for them. This
test is meant to ensure
* that calls to these methods do not include a context from within a
transaction as enumerations are
* already immutable/thread safe and not instrumented.
*
* @author Adam Lewis

*/
public class SyntheticEnumMethodTest extends TestCase{

public static enum A { ZERO, ONE, TWO };

public void testOrdinal() throws Exception {
atomicOrdinalAccess();
}

@Atomic
private void atomicOrdinalAccess(){
A a = A.ZERO;
assertEquals(0, a.ordinal());
}

public void testValueOf() throws Exception {
atomicValueOfAccess();
}

@Atomic
private void atomicValueOfAccess(){
A a = A.valueOf("ZERO");
assertEquals(a, A.ZERO);
}

}

Hi Adam,

The issue is that these methods are defined in java.* classes which are loaded in the boot classpath.

The work around for now is:

public class SyntheticEnumMethodTest extends TestCase{

       public static enum A { ZERO, ONE, TWO };

       public void testOrdinal() throws Exception {

       

               atomicOrdinalAccess();

       }

       @Atomic

       private void atomicOrdinalAccess(){

               A a = A.ZERO;

               Assert.assertEquals(0, ((Enum)a).ordinal());

       }

       public void testValueOf() throws Exception {

               atomicValueOfAccess();

       }

       @Atomic

       private void atomicValueOfAccess(){

               A a = A.valueOf("ZERO");

               Assert.assertEquals(a, A.ZERO);
