[Bug 440685] Re: "-enableassertions -server" not working with tomcat 5.5.26 in Ubuntu 9.04

[Thierry Carrez]

Reproduced with OpenJDK / tomcat6 / Ubuntu 9.10

The issue here is that you are not passing java options, but jsvc options.
jsvc accepts -X and -D options and passes them to the underlying JVM. It does not recognize -enableassertions or -server (see man jsvc). It recognizes -ea for -enableassertions though (undocumented, found in 1.0.1 release notes).

Note that OpenJDK uses -server by default so it should not be needed if
you used OpenJDK. Not sure about Sun's JVM, but it might have the same
default.

So this is not a bug, but maybe we need to document that a little better
since the name is misleading (JAVA_OPTS).

** Package changed: tomcat5.5 (Ubuntu) => tomcat6 (Ubuntu)

** Changed in: tomcat6 (Ubuntu)
   Importance: Low => Wishlist

** Changed in: tomcat6 (Ubuntu)
       Status: New => Triaged

** Summary changed:

- "-enableassertions -server" not working with tomcat 5.5.26 in Ubuntu 9.04
+ Make it clearer that JAVA_OPTS is about JSVC options

** Description changed:

- Binary package hint: tomcat5.5
+ JAVA_OPTS is somewhat misleading since it is JSVC options and not all
+ Java options are recognized, which leads to bug reports like :
  
  I put that in /etc/default/tomcat5.5:
- 
  JAVA_OPTS="-Xmx1024m -enableassertions -server -XX:MaxPermSize=512m
  -XX:+CMSPermGenSweepingEnabled -XX:+CMSClassUnloadingEnabled
  -Djava.awt.headless=true"
  
  But I got this message:
- 
  Invalid option -enableassertions
  
  Then I move to:
- 
  JAVA_OPTS="-Xmx1024m -ea -server -XX:MaxPermSize=512m
  -XX:+CMSPermGenSweepingEnabled -XX:+CMSClassUnloadingEnabled
  -Djava.awt.headless=true"
  
  and I got:
- 
  Invalid option -server
  
  Then, if I remove '-server':
- 
- JAVA_OPTS="-Xmx1024m -ea -server -XX:MaxPermSize=512m
+ JAVA_OPTS="-Xmx1024m -ea -XX:MaxPermSize=512m
  -XX:+CMSPermGenSweepingEnabled -XX:+CMSClassUnloadingEnabled
  -Djava.awt.headless=true"
  
- tomcat finally start.
+ tomcat finally starts.
  
  But why that? and how can I be sure that tomcat is running with
  assertions and server enabled?
