[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
+ to specify the filesystem location for additional application files such
+ as those for 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"
+ 
+ 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"
+ sudo dpkg-reconfigure tomcat6
+  Accept all default values
+ 
+ Reconfiguration will fail with "sed: -e expression #1, char 44: unknown option to `s'"
+  
+ IMPACT:
+ Minor change to maintainer script; already in development release so limited regression potential.
