Drools 6.50使用JDK 1.8時出錯

我在運行drools-core 6.5.0.Final時出現錯誤，並在騾子中使用簡單的彈簧配置。我使用spring 4.3.5.Final和JDK 1.8。我得到一個錯誤 org.mule.module.launcher.DeploymentInitException：NoSuchFieldError：COMPILER_OPT_ALLOW_RESOLVE_INNERCLASSES_WITH_DOTNOTATION 在org.mule.module.launcher.application.DefaultMuleApplication.init（DefaultMuleApplication.java:205初始化和驗證KieContainer失敗時。請注意，我解壓縮了檔案，檔案中沒有相互衝突的罐子，我只找到了2個Drools特定的罐子，drools-core和drools-decisiontables，都是6.5.0.Final。剩下的依賴關係。POM的唯一擁有所有Spring框架4.3.5.RELEASE和Hibernate 4.3。Drools 6.50使用JDK 1.8時出錯

kieContainer = KieServices.Factory.get().getKieClasspathContainer(); 

    LOG.info(kieContainer.verify().getMessages().toString());

我處理Excel電子表格決策表。

我查找了一個原因，但沒有找到答案。問題似乎與mvel庫有關，但我不知道可能會觸發它。請幫忙！

我可以從堆棧跟蹤的問題是在這裏的春天方法見我實現它在LOG.info失敗下面

 @Override 
public void afterPropertiesSet() throws Exception { 
    kieContainer = ...; 

     LOG.info(kieContainer.verify().getMessages().toString()); 
    try { 


        this.builder=factory.newDocumentBuilder(); 

      } catch (ParserConfigurationException e) {

問題在於類加載器。我做了以下t解決問題：

KieServices ks = KieServices.Factory.get(); 
     kieContainer = ks.newKieClasspathContainer(getClass ().getClassLoader());
