Hello Martin,
The vars are all set up right. And it is "not" an ANT problem. The problem
is that the "java.home" points to JAVA_HOME/jre , if I ever call this method
"System.getProperty("java.home");" it will return to me JAVA_HOME/jre
(/opt/jdk1.6.0_06/jre in my case). And all we want is the pure JAVA_HOME (no
/jre).
So I found this interesting post that explains better:
"println ( System.properties.'java.home' );
prints the path to the JRE for me as well. This is of course not surprising
and exactly as it should be since this is the path to the JVM, not to the
JDK.
I think it is clear that the Ant error message is completely misleading. I
have added a bug report in the Ant Bugzilla (43794).
I think we have to find out what Ant does internally to allow the javac task
to run, so that we know how Ant gets round this problem."
