If your single core is at 32bits use Oracle JDK 7u25 or Ubuntu Open JDK
7, the JDK 7u40 for 32bits will corrupt indexes as stated on the lucene
bug report.

"at least 2 cores and at least 2 GB physical memory"
Until know i'm using a VM with single core and 1GB RAM.
So this will be later for production :)
Thank you Guido.

Strange. When i add "-server" to the arguments, i got everytime the error
on jetty startup
Invalid option -server
Cannot parse command line arguments

It is JVM parameter, example:
JAVA_OPTIONS="-Djava.awt.**headless=true -Dfile.encoding=UTF-8 -server
-Xms256m -Xmx256m"
If you want to concatenate more JVM parameters you do it like this:
JAVA_OPTIONS="-Dsolr.solr.**home=/usr/share/solr $JAVA_OPTIONS"
Take a good look at the format,
Guido.

@Guido: Itried it before and than i thought you marked just the server
options
Because the -sever causes a:
sudo service jetty start
* Starting Jetty servlet engine.
jetty
Invalid option -server
Cannot parse command line arguments
Or should i substitute server with ...?
Options with -server:
JAVA_OPTIONS="-Djava.awt.**headless=true -Dfile.encoding=UTF-8 -server
-Xms256m -Xmx256m -XX:+UseG1GC -XX:MaxGCPauseMillis=50
-XX:+OptimizeStringConcat -XX:+UseStringCache
-Dsolr.solr.home=/usr/share/**solr $JAVA_OPTIONS"

Remember the "-server" which for Java webapps or dedicated Java services
will improve things.
Guido.

@Guido: I reduced the min/max heap size to 256m, i will increase this
on
production server.

So the main problem was that the libs must be copied to the
WEB-INF/lib
directory insteed of the jetty lib/ext directory. Is the fact that you
should you use WEB-INF/lib somewhere documented?

Not so hard switching it to Oracle JDK 7u40.
Just download it and change the JAVA_HOME path in
/etc/default/jetty, so
it's not nescessary to switch java version with
update-java-alternatives
The machine is 64bit :)

Does this work ?
I can suggest -XX:-UseLoopPredicate to switch off predicates.
???
Which version of 7 is recommended ?
