Bug when using Either as an expected record. Left is null

[gertkommer]

I tried to test my pattern with spector and got an exception when I use the Either class in ExpectedRecords. I made a stackoverflow post regarding my issue and mister Rohrmann suggested adding an issue regarding a bug in the Testsink of spector. Link to stackoverflow post https://stackoverflow.com/questions/46239847/

Basically when you use an either<> in the expectedrecords it always fails because left is always null

Thanks for pointing this out. Till is right about the source of the bug. I'm going to fix this in the next release.
I'm not sure if I can come up with a temporary workaround in the meantime.
