when to reconfigure?

The generated-configure.sh files (there are two, one in open, one in 
closed) are supposed to be regenerated and checked in whenever any of 
the open/closed .m4 files are touched.

 From time to time, we get OpenJDK fixes that involve the 
common/autoconf/*.m4 files.  In this case, even if the open 
generated-configure.sh file is updated and checked in as per the normal 
procedure, someone inside Oracle needs to step in and push an update to 
the closed generated-configure.sh.  The closed side of the build will be 
broken until one of us does this.  Yes, this is unfortunate, but we do 
not have a better solution so far.

In summary, you should also look for updates to the .m4 files.
