Constant exceptions in logs due to an extra slash in the URL

Problem

Constant exceptions in logs due to an extra slash in the URL.

Steps to Reproduce

1. Install JIRA and JIRA Agile;
2. Tail the localhost logs;
3. Access JIRA with an extra forward slash in the end of the URL:

   http://localhost:8080/secure/Dashboard.jspa/

Expected Results

It should work without any errors in the logs.

Actual Results

The below exception is thrown in the $JIRA_INSTALL/logs/localhost-*.log file:

Aug 20, 2015 12:15:48 PM org.apache.catalina.core.ApplicationContext log
SEVERE: Unhandled exception occurred whilst decorating page
java.lang.StringIndexOutOfBoundsException: String index out of range: -6
	at java.lang.String.substring(String.java:1955)

Workaround

Enable the Access Log and look for the IP address accessing JIRA with the incorrect URL by comparing the date and time from the exception in the $JIRA_INSTALL/logs/localhost-*.log file.
