Subsection ordering:

Item Ordering:
Fixes having an issue number are sorted by their number, ascending.
There is no ordering by add/update/fix.
Other fixed issues are added to the end of the list, chronologically.
They eventually become mixed with the numbered issues. (I.e., numbered
issues do not "pop up" wrt. others).

form since some components of the JRE, such as JAR verification, give
unexpected results when the standard form is used. A side-effect of the
