Hi,

What would be the recommended Java 1.6 update version for production ES  
installation on Linux? I saw that Shay recommended Sun Java 1.6u23 in one  
mail thread, is this still valid recommendation or using the most recent  
update version is better? (as of writing u25 is available).

Thanks,  
Lukas

IMHO always most recent because of security;

I recommended 1.6u23 since it was the latest one. 1.6u25 (latest) is recommended (at least I haven't heard anything bad about it).
