Source code misaligned when partial mocking private methods using JMockit

[Salil Surendran]

Hello Friends,
I have a class that I am partially mocking using NonStrictExpectations

 @Test
    public void testGetMessageFromCampaign() {
		
		final CampaignSelector campaignSelector = new CampaignSelector();

		new NonStrictExpectations(campaignSelector) {
			{
				Deencapsulation.invoke(campaignSelector,"getOptimizationModelId",CampaignPlacementBo.class);
				returns((Long)null);
				
			}
		};
		
				
		campaignSelector.getMessageFromCampaign();
	}

The problem is that when I use Deencapsulation.invoke() to mock a private method it messes up the source code of the CampaignSelector class and hence when I debug into the getMessageFromCampaign() method the source code is misaligned in Eclipse. I understand that JMockit redefines classes but this only happens when private methods are mocked and not public. Any way to get around this problem?
