Unable remove a rule package when it was added after it has been added and removed.
I have seen the issue  [#JBRULES-358].  My test go a little far than [#JBRULES-358]. 
I remove the package again when it was added for the seconn time, then an exception was thrown.

 My test case is:

    
    public void testRuleBaseRemove() throws Exception
    {
        RuleBase ruleBase = RuleBaseFactory.newRuleBase();
        File file = new File("test.drl");
        
        //add and remove
        PackageBuilder builder = new PackageBuilder();
        builder.addPackageFromDrl(new FileReader(file));
        Package pkg = builder.getPackage();
        ruleBase.addPackage(pkg);
        ruleBase.removePackage(pkg.getName());
        
        //add and remove again
        builder = new PackageBuilder();
        builder.addPackageFromDrl(new FileReader(file));
        pkg = builder.getPackage();
        ruleBase.addPackage(pkg);
        ruleBase.removePackage(pkg.getName());
    }

the exception is throw:
