What is the best java for debian-amd64 ?

[hans-u@t-online.de (Hans-J. Ullrich)]

Hi all,

as there are many java versions installable, what is the best one to use in 
amd64-systems ? What are the differences ? I saw gcj, gij, gdk, java. Can 
someone tell me, which should be used ? Ia ma very confused. 
Update-alternatives is giving me these choices:

There are 8 alternatives which provide `java'.

  Selection    Alternative
-----------------------------------------------
          1    /usr/bin/gij-4.1
          2    /usr/lib/jvm/ia32-java-6-sun/jre/bin/java
          3    /usr/lib/jvm/java-gcj/jre/bin/java
          4    /usr/bin/gij-4.3
*         5    /usr/lib/jvm/java-6-sun/jre/bin/java
          6    /usr/bin/gij-4.2
          7    /usr/lib/jvm/ia32-java-1.5.0-sun/jre/bin/java
 +        8    /usr/lib/jvm/java-6-openjdk/jre/bin/java

Press enter to keep the default[*], or type selection number:

I choose 5. What is this "+"-sign meaning ?

Questions, questions, questions....

Thanks for any help !


Kind regards
