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