Symptoms

 When we attempt to open the worksheet with a relatively small volume of data, the performance is bad.

 The Worksheet continues to display the message 'Loading' but it never come up..
    
 Also enabled the Java console and re-tested to determine if there are any error messages.

  After re-testing the following error message was displayed then everything froze in the Java client log:.
