DO NOT REPLY [Bug 47276] New: Repeated log warnings when /dev/urandom is not readable

https://issues.apache.org/bugzilla/show_bug.cgi?id=47276

           Summary: Repeated log warnings when /dev/urandom is not
                    readable
           Product: Tomcat 5
           Version: 5.5.27
          Platform: Other
        OS/Version: AIX
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Catalina
        AssignedTo: dev@tomcat.apache.org
        ReportedBy: Tim.Whittington@orionhealth.com


When the /dev/urandom device is not readable by the Tomcat process, we see
repeated "Failed to close randomIS" messages logged at the WARN level.

The issue appears to be in ManagerBase.setRandomFile - if the random device is
not readable it fails to open the file (i.e. construct the FileInputStream - at
least on AIX this fails immediately), and then blindly tries to close the
inputstream resulting in an NPE and the "Failed to close randomIS" message.

A quick null check before closing would probably fix this.
A solution that warned once on an inaccessible random device and didn't try to
reopen it thereafter might be better.

It is duplicate of bug 46967, that is already fixed in the 6.0.x branch.
