Hoss Man commented on SOLR-5241:
--------------------------------
I don't think so, but maybe i don't fully understand what the FreeBSD blackhole
does.
The test never attempts to open any sockets to these URL objects -- the problem
so far (that i can see) is just that by nature of being java.net.URL, there is
a DNS check when the equals/hashCode methods get used and that seems to be the
speed problem when the urls contain "example.com" ... so i figured using a
"safe" IP would prevent that...
http://www.eishay.com/2008/04/javas-url-little-secret.html
is there any reason the freebsd blackhole would affect dns lookups on
"127.42.42.42" even if the URL class did decide to try to "resolve" that IP as
a hostname (i don't think it does) ?
> SimplePostToolTest is slow on some systmes - likely due to hostname
