Michael Moser commented on NIFI-3304:
-------------------------------------
According to Oracle's Java 8 documentation \[1\] the defaults are currently
-XX:ReservedCodeCacheSize=240m
-XX:+UseCodeCacheFlushing
These seem to already align with our Admin Guide recommendations, so I think we
can remove this section of the Admin Guide.
With Java 7, the default ReservedCodeCacheSize was 48m and codecache flushing
was buggy \[2\] so our older Admin Guide recommendations made more sense.

> In the Administration guide, section Bootstrap properties, there is a
> paragraph about Java 8 handling of codecache, the listed properties are
> accurate for Java version 7, but for Java version 8, one has changed
> This is correct for Java version 7:
> java.arg.8=-XX:CodeCacheFlushingMinimumFreeSpace=10m
> But for Java version 8, it should be
> java.arg.8=-XX:CodeCacheMinimumFreeSpace=10m
