0000006c webapp E com.ibm.ws.webcontainer.webapp.WebApp logServletError SRVE0293E: [Servlet Error]-[Stores Request Servlet]: java.lang.NullPointerException at java.net.URLDecoder.decode(URLDecoder.java:130)
  
JR42439: CMVC 220771 - handle nullpointerexception when cookie.getValue()is null and passed into URLDecoder in RuntimeServletFilter class


Solution

The NPE should be handled in your code, and if cookie value is null, it should be printed as "cookie is null" instead of throwing NPE.
