Two functions with Janino compiler end up with out of memory error
------------------------------------------------------------------

                 Key: JBRULES-1013
                 URL: http://jira.jboss.com/jira/browse/JBRULES-1013
             Project: JBoss Rules
          Issue Type: Bug
      Security Level: Public (Everyone can see)
         Environment: Ubuntu Feisty, JDK 1.4 or 1.5
            Reporter: Pierre Paysant-Le Roux
         Assigned To: Mark Proctor


Compiling a simple rules file containing two functions with janino causes an out of memory error.
Rules file example :
package test
 
package test
 
import test.TestThreads.Fact;

function boolean func1() {
	return true;
}

function boolean func2() {
	return true;
}

rule "test"
when
	Object()
then
	System.out.println("fired");
end

and the code that generate the error :

package test;

import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Properties;

import org.drools.compiler.DroolsParserException;
import org.drools.compiler.PackageBuilder;
import org.drools.compiler.PackageBuilderConfiguration;

public class Test {

    public static void main (String[] args) {
        Properties properties = new Properties();
        properties.setProperty("drools.dialect.java.compiler", 
                               "JANINO");
        PackageBuilderConfiguration pkgBuilderCfg = new PackageBuilderConfiguration(properties);
        PackageBuilder builder = new PackageBuilder(pkgBuilderCfg);
        try {
            builder.addPackageFromDrl(getSource());
        } catch (DroolsParserException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    
    private static InputStreamReader getSource() {
        return new InputStreamReader(Test.class.getResourceAsStream( "Sample.drl" ));
    }
}
After profiling, I identified that the problematic line is the 146 one in class JaninoJavaCompiler. It causes the loadIClass method to loop with a cycle that I don't understand. Placing a breakpoint on the line 91 of JaninoJavaCompiler class permit to observe the loop iterations.
