[ITK] Problem with LabelShapeStatisticsImageFilter

[Lowekamp, Bradley (NIH/NLM/LHC) [C]]

Hello,

Did you compile SimpleITK yourself? What OS, architecture and Java version are you using?

Looking at this filter [1], I see both of these problematic methods are returning “uint64_t” in C++. There appears to be some problem with the conversion of integers. What is the return type in your Java for getNumberOfLabels()? Is may be BigInteger?

HTH,
Brad
