Hi together,
after updating the Jetty to the newest 9.1.4 version, in order to support my
Spring4/Java 8 web app, I run into a strange NPE problem.
I get this error:
java.lang.NullPointerException
at
org.apache.jsp.views.secured.report.create_002delement_002dfragment_jsp._jspx_meth_c_if_0(create_002delement_002dfragment_jsp.java:315)
at
org.apache.jsp.views.secured.report.create_002delement_002dfragment_jsp._jspService(create_002delement_002dfragment_jsp.java:119)
at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:111)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:790)

org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:411)
at
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:473)
If I am right, the problem is the el-3 library, which will treat null values in
a different way. I found some issues in bug tracking systems for Tomcat,
Glassfish and even in Jetty – but I was not able to figure out, how to solve
this problem.
I want to avoid writing:
<c:if test=„${not empty nonExisting && nonExisting}“>
Is there anything I can do in order to not modify the existing JSP files?
Best
