Suggestion:

Labels of the form [Rel-wnf]{.jbs-label} (e.g. [9-wnf]{.jbs-label}) should be used to indicate that a bug is not going to be fixed in a release that it is applicable to, or any earlier releases. For example, [11-wnf]{.jbs-label} states it won't be fixed in JDK 11 and implicitly indicates it won't be fixed in JDK 8 either).
