CNTR0020E: 在 bean“BeanId(BizServer_jar#BizServer.jar#StatelessBizServer, null)”上处理方法“executeSQL”时发生非应用程序异常。异常数据：javax.ejb.EJBException: ORA-00933: SQL command not properly ended

参考 http://www-1.ibm.com/support/doc ... amp;uid=swg1PK35736
好像是WAS处理多线程的缺陷，在5.1.1.14得到了修改

with multiple threads

[27/09/06 12:58:35:378 BST] 6cc81c21 ExceptionUtil E CNTR0020E:
Non-application exception occurred while processing method

HashMap attempted by Thread[ORB.thread.pool : 1,5,main]
java.util.ConcurrentModificationException: concurrent access to
HashMap attempted by Thread[ORB.thread.pool : 1,5,main]

java.util.ConcurrentModificationException: concurrent access to
HashMap

   at java.util.HashMap.transfer(HashMap.java(Compiled Code))
   at java.util.HashMap.resize(HashMap.java(Inlined Compiled
Code))
   at java.util.HashMap.addEntry(HashMap.java(Compiled Code))
   at java.util.HashMap.put(HashMap.java(Compiled Code))
   at org.apache.wsif.util.WSIFUtils.isJavaKeyword

    The underlying cause of the problem is that the
java.util.HashMap is not thread-safe, so the concurrent access
causes unpredictable results.
