[news.eclipse.tools] Ant problem : Modern compiler is not available....

[kfx@xxxxxxx (Fx)]

Hi all,
I've got a probleme with ant :
When I try to execute some tasks an error occured but sometimes execution
is ok !

Here the message returned:
"Modern compiler is not available - using classic compiler"
"A common solution is to set the environment variable JAVA_HOME to your
jdk directory"

I've set the env variable JAVA_HOME in the OS. Maybe it's necessary to set
in an other place ?

Thanks for your help
Best regards.
