Not sure I can be much assistance on this one. Does the Python and JVM have the same machine architectures? Multiple threads indicate that this is a bug of some...
For reference here is the same code in JPype. ``` import sys import jpype from jpype.types import * from jpype import JImplements, JOverride jpype.startJVM() @JImplements('java.util.function.IntSupplier') class OneSupplier: @JOverride def getAsInt(self):...
