JDK 11u policy notice: no more enhancements

[Andrew Haley]

Now that 17u is the current stable OpenJDK release, we need to remind
contributors of the rules for 11 updates. In particular, there are some
proposals for backports of performance improvements which we should not
allow. 11u is a stable branch to be maintained above all else.

---------------------------------------------------------------------------

In general, new features and performance improvements from later JDK
releases will not be accepted. There may be exceptions in some cases,
but they will be very unusual, perhaps in cases of gross performance
problems on some systems. We'll address these as they arise.

Any reasonable bug fix that improves the stability, security, or performance
of JDK 11u in a significant way should be considered.

Bugs fitting into one or more of the following categories will usually
be accepted for approval:

      CPU fix merges (i.e. critical security bugs)
      TZData updates
      Test fixes (and extra tests - more testing is always welcome!)
      Changes to root CACerts
      Changes to the build number
      Fixes specific to downstream builders' projects
      i18n / l10n changes

In addition this list, we will consider

      Build system improvements, particularly for stability and reproducibility
      Changes necessary to make 11u work on new operating systems and hardware.
