Description Ryan Lubke 2002-03-20 20:15:28 UTC 
Given:

<c-rt:import url='<%= null %>'/>

Generates the following:
java.lang.NullPointerException
	at o.a.t.s.tag.common.core.ImportSupport.isAbsoluteUrl(ImportSupport.java:481)
	at o.a.t.s.tag.common.core.ImportSupport.isAbsoluteUrl(ImportSupport.java:467)
	at o.a.t.s.tag.common.core.ImportSupport.doStartTag(ImportSupport.java:150)
	at o.a.jsp.negativeUrlNullTest$jsp._jspService(negativeUrlNullTest$jsp.java:167)


Section 7.4, page 7-59 of the PD Spec:

"If url is null or empty, a JspTagException is thrown."

This works fine with the EL version if the import tag.
