[Bug 654549] Re: [SRU] Tomcat6 fails to upgrade if JAVA_OPTS contains /

[James Page]

** Description changed:

  IMPACT:
  This bug will impact tomcat6 installs upgrading to Maverick and updates in Maverick itself; its fixed in Natty.
  
- Using the '/' character in JAVA_OPTS is quite common - its normally uses
+ Using the '/' character in JAVA_OPTS is quite common - its normally used
  to specify the filesystem location for additional application files such
  as those for Hudson:
  
-  -Dhudson.home=/home/hudson
+  -Dhudson.home=/home/hudson
  
  Updates/upgrades using this type of option will fail.
  
  FIX:
  tomcat6.postinst uses sed to parse various debconf answers into a template which is used to generate /etc/default/tomcat6; this currently uses '/' as the pattern delimiter - the fix switches this to '%' which is unlikely to be used in JAVA_OPTS.
  
  PATCH:
  See linked branch
  
  TEST CASE 1:
  sudo apt-get install tomcat6
  sudo dpkg-reconfigure tomcat6
-  Accept all default for user and group
-  Add an additional parameter to JAVA_OPTS - "-Dtest.dir=/var/log/nonsense"
+  Accept all default for user and group
+  Add an additional parameter to JAVA_OPTS - "-Dtest.dir=/var/log/nonsense"
  
  Reconfiguration will fail with "sed: -e expression #1, char 44: unknown
  option to `s'"
  
  TEST CASE 2:
  sudo apt-get install tomcat6
  sudo vi /etc/default/tomcat6
-  Add an additional parameter to JAVA_OPTS - "-Dtest.dir=/var/log/nonsense"
+  Add an additional parameter to JAVA_OPTS - "-Dtest.dir=/var/log/nonsense"

  IMPACT:
  Minor change to maintainer script; already in development release so limited regression potential.
