  1. Trouble: NativeOperation public static org.atl.engine.vm.nativelib.ASMNumber org.atl.engine.vm.nativelib.ASMInteger.operatorMinus(org.atl.engine.vm.StackFrame,org.atl.engine.vm.nativelib.ASMInteger,org.atl.engine.vm.nativelib.ASMNumber)
    Cause: You use negative integer to compare: e.g. if self.upper = -1 ...
    Solutions: Use (0-x) operation: e.g. if self.upper = (0-1) ... or change your comparaison if it is possible: e.g. if self.upper < 0 ...

    Cause: Your called rule doesn't return the good type (problably any)
    Solution: Add a return type on your called rule by adding the do clause: e.g.
rule myCalledRule() {
   out : XML!Element...
 do {
