            The <q>JDK check</q> API is a special contract between the core/startup

            module and branded applications on top of it, that allows to perform

            a check for a special class to be available during execution of 

            NetBeans based application. If it is missing a warning dialog is shown

            and user can cancel the execution. The contract is based on 

            branding keys from 

            <a href="http://www.netbeans.org/source/browse/core/startup/src/org/netbeans/core/startup/Bundle.properties?rev=1">
