我正在尝试开除规则。但是，我收到以下异常：

代码：
System.setProperty("drools.dialect.java.strict", "false");
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory
.newKnowledgeBuilder();
Map<String, TagEvent> map = RulesEngineDAO.selectAllConfigDetails();
for (TagEvent tagEvent : map.values()) {
kbuilder.add(ResourceFactory.newReaderResource(TagEventRuleBuilder
.buildRuleFromTemplate(tagEvent)), ResourceType.DRL);
}
Collection<KnowledgePackage> pkgs = kbuilder.getKnowledgePackages();
KieBaseConfiguration kbaseConfiguration = KnowledgeBaseFactory
.newKnowledgeBaseConfiguration();
kbaseConfiguration.setOption(EventProcessingOption.STREAM);
final KnowledgeBase kbase = KnowledgeBaseFactory
.newKnowledgeBase(kbaseConfiguration);
kbase.addKnowledgePackages(pkgs);
KieSessionConfiguration sessionConf = KnowledgeBaseFactory
.newKnowledgeSessionConfiguration();
sessionConf.setOption(ClockTypeOption.get("realtime"));
ksession = kbase.newStatefulKnowledgeSession(sessionConf, null);
Map<String, TagEvent> globalMap = RulesEngineDAO.selectAllConfigDetails();
ksession.setGlobal("map", globalMap);
new Thread() {
@Override
public void run() {
ksession.fireUntilHalt();
}
}.start();
我正在调用上面的代码进行会话。一切都很好，并且能够参加知识会议。但是，就行
ksession.setGlobal("map", globalMap);
，抛出以上异常。
正在使用模板生成DRL文件的Am也正在生成DRL文件。在模板和生成的DRL文件中：
global java.util.Map<String,TagEvent> map;
我真的无法弄清楚为什么在运行代码时会出现此错误。
使用以下代码段：
KnowledgeBuilderErrors errors = kbuilder.getErrors();
if( errors.size() > 0 )
{
for( KnowledgeBuilderError error : errors )
{
System.err.println( "Errors : "+error );
}
throw new IllegalArgumentException( "Could not parse knowledge." );
}
现在我遇到以下错误：
