[rules-users] JUnit testing problem

[J Michael Dean]

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.
