    on #1021 in 
[logs](https://s3.amazonaws.com/archive.travis-ci.org/jobs/137973583/log.txt) I 
can see
    
    **ParagraphActionsIT.testRemoveButton**
    ```
    
org.apache.zeppelin.integration.ParagraphActionsIT.testRemoveButton(ParagraphActionsIT.java:152)
    03:13:23,791  INFO org.apache.zeppelin.AbstractZeppelinIT:59 - Finished.
    03:13:53,820 ERROR org.apache.zeppelin.AbstractZeppelinIT:153 - Exception 
in ParagraphActionsIT while testRemoveButton 
    org.openqa.selenium.NoSuchElementException: Unable to locate element: 
{"method":"xpath","selector":"//div[@class='modal-dialog'][contains(.,'delete 
this paragraph')]//div[@class='modal-footer']//button[contains(.,'OK')]"}
    Command duration or timeout: 30.03 seconds
    ```
    
    when the browser gets trapped in this state, as one can see - there is 
indeed no modal dialog on the screen

    So may be its [previous 
line](https://github.com/apache/zeppelin/blob/master/zeppelin-server/src/test/java/org/apache/zeppelin/integration/ParagraphActionsIT.java#L146),
  `//ul/li/a[@ng-click='removeParagraph()']` that fails to trigger paragrpah 
removal here?
