处理方案：

可以看到是中间件的hazelcast类和应用冲突了，需要优先加载应用的类，两种处理方案：

1.在应用的WEB-INF目录添加apusic-web.xml

<?xml version="1.0" encoding="UTF-8"?> 
<aas-web-app error-url=""> 
<class-loader delegate="false">
<property name="ignoreParentsFiles" value="true"></property>
<property name="ignoreClassPrefix" value="com.hazelcast"></property>
<property name="ignoreResources" value="META-INF/services/javax.cache.spi.CachingProvider;com.hazelcast"></property>
</class-loader>
</aas-web-app>

2.添加jvm参数-Dcom.sun.enterprise.overrideablejavaxpackages=指定冲突类包名
这里:-Dcom.sun.enterprise.overrideablejavaxpackages=javax.cache
