CPU spins when :matches expression contains "*************"

                 Key: JSIEVE-49
                 URL: https://issues.apache.org/jira/browse/JSIEVE-49
             Project: JAMES jSieve
          Issue Type: Bug
          Components: JSieve (Main)
    Affects Versions: 0.2
            Reporter: Boris Burtin


A Zimbra customer reported that the mail delivery thread goes into a CPU spin 
when jSieve evaluates the following rule:

if anyof (header :matches "from"
"**********************************************[email protected]" ,
 header :is "subject" "5" )
{
    fileinto "Whatever";
    stop;
}

I'm able to work around the problem by disallowing values that contain more 
than four asterisks in succession, but this should be  fixed in jSieve.  Here's 
the link to the Zimbra bug:
