Continuing to have problems - can use Drools in RCP but when I try to JUnit test, I cannot instantiate a PackageBuilder.  With the following code fragment:

@BeforeClass

public static void setUp() throws Exception {

Reader source;

PackageBuilderConfiguration pkgConfig = new PackageBuilderConfiguration();

JavaDialectConfiguration javaDialectConf = (JavaDialectConfiguration) pkgConfig.getDialectConfiguration("java");

javaDialectConf.setCompiler(JavaDialectConfiguration.ECLIPSE);

if (pkgConfig == null ) {

System.out .println("Error - null package configuration");

} else {

System.out .println("Package configuration is not null"); // NOTE THAT THIS EXECUTES SO NOT NULL

}

final PackageBuilder builder = new PackageBuilder(pkgConfig); // CRASH OCCURS IN THIS LINE OF CODE

I get the following trace:

Package configuration is not null

java.lang.NullPointerException

[MVEL] Notice: Possible incorrect version of ASM present (3.0 required).  Disabling JIT compiler.  Reflective Optimizer will be used.

I had similar issue a number of weeks ago that never resolved, but subsequently have upgraded Eclipse to 3.3.2, running on OSX Leopard.  I cannot locate a ASM library and obviously the error message is hinting at that.

Any assistance will be appreciated.  I hate proceeding without JUnit testing in place.
