possible incompatilbilty with jdk8

[mustafaiman]

EqualsVerifier.forClass(ConnectionFactoryImpl.class).usingGetClass().withPrefabValues(ManagedConnectionFactoryImpl.class,
            mock(ManagedConnectionFactoryImpl.class), mock(ManagedConnectionFactoryImpl.class))
            .suppress(Warning.NONFINAL_FIELDS).suppress(Warning.TRANSIENT_FIELDS).verify();

Above test works fine with jdk1.7.0_71 but it fails with the following error on Jdk1.8.0_51. I mocked ManagedConnectionFactoryImpl using Mockito. However it does not matter if I mock it or new ConnectionFactoyImpl() there. ConnectionFactoryImpl class has one reference to ManagedConnectionFactoryImpl but it does not use it in equals or hatched method.

FYI
ConnectionFactoryImpl has a field

private Reference ref;

adding the following snippet makes the test pass

.withPrefabValues(Reference.class, mock(Reference.class), mock(Reference.class))

[jqno]

I've reproduced this. Nice catch. Thanks for the update too; the problem had indeed to do with the Reference class.

I'll fix this in the next release. In the mean time, using withPrefabValues is indeed the workaround that I would have suggested :).

[jqno]

This is fixed in version 1.7.4, which was just released.
