      FULL PRODUCT VERSION :
      java version "1.7.0_79"
      Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
      Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)

      ADDITIONAL OS VERSION INFORMATION :
      Windows 8.1

      A DESCRIPTION OF THE PROBLEM :
      An Exception is thrown if the mouse gets clicked a few times and is moved on the webview.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      create a simple WebView and add the following html with contentType "text/html" to the webview

      <html >
      <head >
      <style type="text/css">
      body {padding-top: 0; padding-right: 2; padding-bottom: 0; padding-left: 2; margin-top: 0;
      margin-right: 0; margin-bottom: 0; margin-left: 0}
      p {padding: 0; margin: 0; font-size: 15px; line-height: 1.2}
      .error {color: red}
      #error {color: red}
      .success {color: #069f00}
      #success {color: #069f00}
      .notice {color: #b77213}
      #notice {color: #b77213}
      .tipp {color: #426aff}
      #tipp {color: #426aff}
      .keyshortcuts {color: #426aff}
      #keyshortcuts {color: #426aff}
      .key {padding-right: 1cm}
      .indent {margin-left: 1cm}
      .doubleindent {margin-left: 2cm}
      </style>
      </head>
      <body >
      <div id="error" >
      <p >an error </p>
      </div>
      <div id="success" >
      <p >a success </p>
      </div>
      <div id="notice" >
      <p >a notice </p>
      </div>
      <div id="tipp" >
      <p >a tipp </p>
      </div>
      <div id="keyshortcuts" >
      <table id="keyshortcuts" >
      <tr />
      </table>
      </div>
      </body>
      </html>

      now start the application.
      click the left mouse-Button two times hold the mouse-button down move it and click it a third time and the exception will occur. The click timing must match a 3-click on the left mouse button. Its a bit tricky to get it but it occurs almost always.
      (The bug does NOT occur if no html is loaded!!!)

      the same Bug exists in Java 8 update 45 64-bit on Windows 8.1. The only difference is the exception
