title: NoSuchMethodError at SXSSFWorkbook.dispose() | Apache POI
body: <p>We are using Apache POI's SXSSFWorkbook implementation to generate large size excel reports in our applications. 
  As this implementation puts lots of temporary files in the memory while generating the excel, we are using dispose() method to clean those off from the memory.</p>
  
  <p>Unfortunately, we are encountering NoSuchMethodError for this method. We are using poi-ooxml-3.12.jar version. 
  As a first step of verification I checked if there is any conflict in jar versions, but no it looks fine. Also there are no duplicate jar.</p>
  
  <p>We have cluster of servers (WildFly-13) and this piece of code is working perfectly fine in Master server, but failing only in Slaves.</p>
  
  <p>Can anyone help me point out possible issue?</p>
