[jira] Updated: (AXIS-2189) empty boolean attribute -> NPE

toby cabot updated AXIS-2189:
-----------------------------

    Attachment: axis-empty-boolean-patch.txt

This is a workaround, but I don't think it's a fix.  I added an explicit check that throws a NumberFormatException if the boolean is empty.  There's already code in makeBasicValue() that throws if it can't parse the boolean, so I guess this acceptable behavior.  The result is still pretty ugly, i.e. stack traces in the log and result messages with "java.lang" in them, but at least they indicate a bad boolean rather than an NPE.

> If a document has a boolean attribute, an empty instance of that attribute will trigger a NullPointerException during deserialization.  For example, one of the schemas I use has
> <attribute name="reportIfEmpty" type="xsd:boolean" default="false" />
> If the inbound document contains
>     <reportSpec reportIfEmpty="" reportName="1" reportOnlyOnChange="false">
