When adding resources using both MVEL and Java dialects the JavaDialect constructor fails when dialectData is found and stored. ------------------------------------------------------------------------------------------------------------------------------- Key: JBRULES-3366 URL: https://issues.jboss.org/browse/JBRULES-3366 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-compiler Affects Versions: 5.3.1.Final Environment: Linux Reporter: Alan Zall Assignee: Mario Fusco In the constructor of JavaDialect, if pkg.getDialectRuntimeRegistry().getDialectData( ID ) returns a non null value, then a null is passed into the PackageStore constructor. if ( pkg.getDialectRuntimeRegistry().getDialectData( ID ) == null ) { data = new JavaDialectRuntimeData(); this.pkg.getDialectRuntimeRegistry().setDialectData( ID, data ); data.onAdd( this.pkg.getDialectRuntimeRegistry(), this.packageBuilder.getRootClassLoader() ); } this.packageStoreWrapper = new PackageStore( data, this.results ); is fixed by: if (( data = (JavaDialectRuntimeData) pkg.getDialectRuntimeRegistry().getDialectData( ID )) == null ) { data = new JavaDialectRuntimeData(); this.pkg.getDialectRuntimeRegistry().setDialectData( ID, data ); data.onAdd( this.pkg.getDialectRuntimeRegistry(), this.packageBuilder.getRootClassLoader() ); } this.packageStoreWrapper = new PackageStore( data, this.results );
