    Description

      Steps to Reproduce

      run the attached test case (isolated example)

      zkfiddle: http://zkfiddle.org/sample/1e8gaj7/14-EL-exception-on-import (more integrated with ZK)

      Current Result

      importing a previously failed/cached class name causes an exception

      The class [zk.support.test.ImportHandlerTest] could not be imported 
        as it conflicts with [org.zkoss.zel.ImportHandler$NotFound] which has already been imported
      org.zkoss.zel.ELException: The class [zk.support.test.ImportHandlerTest] could not be imported 
        as it conflicts with [org.zkoss.zel.ImportHandler$NotFound] which has already been imported
      	at org.zkoss.zel.ImportHandler.importClass(ImportHandler.java:135)
      	at zk.support.test.ImportHandlerTest.testReImportAfterFailedResolve(ImportHandlerTest.java:15)
      

      Expected Result

      a cached ImportHandler$NotFound should not prevent a correct import later
      instead the successfully imported class can replace the cached NotFound
