WSDL2Java bug??

[Shinde, Uma]

I'm using the Alpha 3 release. Tried the WSDL2Java on  a wsdl where the <service> had 
an empty doucmentation element as follows.

<service name="MyBubbleSoapService">
<documentation></documentation> 
<port name="MyBubbleSoapPort" binding="tns:MyBubbleSoapBinding">
<soap:address location="http://www.mybubble.com:8080/soap/servlet/rpcrouter"; /> 
</port>
</service>

This resulted in a null pointer exception. Here's the stack trace.

java.lang.NullPointerException
    at org.apache.axis.wsdl.toJava.JavaWriter.writeComment(JavaWriter.java:200)
    at 
org.apache.axis.wsdl.toJava.JavaServiceImplWriter.writeFileBody(JavaServiceImplWriter.java:103)

    at org.apache.axis.wsdl.WSDL2Java.emit(WSDL2Java.java:353)
    at org.apache.axis.wsdl.WSDL2Java.main(WSDL2Java.java:486)

I did get rid of the exception by adding a space - "<documentation> </documentation>"
