I noticed since block #481824 and onward, my bitcoinj library started throwing this exception when trying to parse blocks:

Exception in thread "main" java.lang.NegativeArraySizeException

I was able to parse blocks before this point no problem.  Anyone have the same problem?

....and this is probably due to segwit2x activation @ 481824...doh!

...and now I see there is a segwit branch for bitcoinj which I'm sure deals with the issue.  Sorry to bug everyone.  Case closed.
