jbc2mpl generated code with mismatching type which causes failure when code is executed.

1. Test.java

public class Test {

private byte byteVar;

public static void main(String[] args) {
    Test test = new Test();
    test.nestedByteVar();
    System.out.println(test.byteVar);
}

void nestedByteVar() {
    byteVar = 1;
    Nested nested = new Nested();
    nested.incByte();
}

class Nested {
    void incByte() {
        byteVar += 1;
    }
}

}
