Description

ProfileOutputServlet sanitizes the input URL but fails when the query string contains dot or hyphen. These are valid characters for the hostname.

Example URL part:

/prof-output/async-prof-pid-122466-cpu-1.svg?host=myhost-1.example.com&port=16010 

In this case the user gets the following error message:

HTTP ERROR: 500
Problem accessing /prof-output/async-prof-pid-122466-cpu-1.svg. Reason:
    java.lang.RuntimeException: Non-alphanumeric data found in input, aborting.
