PH12798: LIBERTY RESPONDS WITH HTTP 500 WHEN URL CONTAINS AN ASTERISK

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Liberty responds with HTTP 500 when URL contains an asterisk
  We run a Liberty WebApplication that listen to URL:
  http://server:port/spcics/HelloWorld.
  
  If the URI, that calls that application, contains an asterisk,
  then Liberty throws an Internal Server error and responds with
  HTTP 500.
  For example: http://server:port/spcics/*
  
  Response code 500 means an "Internal Server error", but that is
  the wrong code. Instead we would expect a 404 (Not Found).
  Furthermore log writes many messages containing a URL Parse
  Exception.
  

Local fix

• HTTP response code change

  ****************************************************************
  * PROBLEM DESCRIPTION: CICS Liberty JVM server returns HTTP    *
  *                      500 response code when the URL          *
  *                      contains asterisk.                      *
  ****************************************************************
  A HTTP request is sent to a CICS Liberty JVM server, the URL
  contains an asterisk. CICS returns a 500 internal server error,
  and diagnostics are written to the DFHJVMTRC, STDERR and
  messages.logs files.
  

Problem conclusion

• CICS has been changed to return HTTP 404 response code when
  the URL contains an asterisk, and also reduce the amount of
  diagnostics issued.
