jaxb:globalBindings optionalProperty="primitive" causes NullPointer in xjc

My intent here is to force isControllingMember() method have a primitive boolean return type, as opposed to Boolean.

Running my Ant task causes this exception:

If I modify bindings.xml like this:

**bindings.xml**<?xml version="1.0" encoding="UTF-8"?>
<jaxb:bindings
    xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" version="2.1">

    <jaxb:globalBindings optionalProperty="primitive" generateIsSetMethod="false" />
</jaxb:bindings>

then my ShareholderType class gets successfully generated. Unfortunately, adding generateIsSetMethod attribute causes optionalProperty=“primitive” not to work anymore for the boolean field (now the return type on isControllingMember() is Boolean), so this is not a workaround.

I’m hitting this problem. What’s the plan here?
