Searching for nonexistent project/issues in Sun ONE app server causes NullPointerException

Searching for a number (eg. '123' to find ABC-123) causes the following error in JIRA 3.3.1:

javax.servlet.jsp.JspException: java.lang.NullPointerException

Looking in the _projectnotfound_jsp.java file, the NPE is occurring at the line:

if (_jspx_th_webwork_text_0.doEndTag() == javax.servlet.jsp.tagext.Tag.SKIP_PAGE)

Similarly when searching for an issue key that doesn't exist ('foo-12345'), one gets an error in issuenotfound.jsp:
