[jboss-jira] [JBoss JIRA] Closed: (JBRULES-1013) Two functions with Janino compiler end up with out of memory error

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) Components: Drl Parser/Builder Affects Versions: 4.0.0.GA Environment: Ubuntu Feisty, JDK 1.4 or 1.5, Drools Snapshot Reporter: Pierre Paysant-Le Roux Assigned To: Mark Proctor Fix For: 4.0.2 Compiling a simple rules file containing two functions with janino causes an out of memory error. Rules file example : package test 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.
