Code change for JDK-8240261 uses $(TOPDIR)/make/templates/gpl-cp-header to generate source files but it is not available in all source bundles used for builds. Request to back out the change. The changeset is a direct output of 'hg backout' command. You can see the webrev at https://cr.openjdk.java.net/~weijun/8240980/webrev.00 Thanks, Max
