NoSuchMethodError after applying 6.4.0 hotfix

Issue description

After applying a cumulative hotfix for TIBCO JasperReports^® Server v6.4.0 some reports fail with the following error:

java.lang.NoSuchMethodError: net.sf.jasperreports.engine.fill.BaseReportFiller.getUsedPageWidth()I

Cause and solution

The latest hotfix for JasperReports Server 6.4.0 contains an additional step which is not usually present in most hotfix packages:

• Delete the files listed in the section "Deleted files" from the web application files structure.

The mentioned section lists the ../WEB-INF/lib/jasperreports-6.4.1.jar file, which you have to delete prior to applying the hotfix. Since this step is unique to the latest version of 6.4.0 hotfix, it is fairly easy to overlook
