I've been finding that since I got my new MacBook Pro
and installed Java 8
on it, all of the Java Applications
that I've been running have been taking an extremely long time to start or to establish network connections. This didn't seem to affect Java Applications
that didn't use the network however. Turns out that the problem is to do with the local machine's hostname resolution and is easily fixed.
First you need to find the hostname of your Mac
. You do this from System Preferences
. Click the Sharing
icon in System Preferences
You will see a box that shows the Computer Name
, under that will be the hostname ending in .local
. That's what you will need, so take note of it. In my case it was Enzyme.local
The next step is to update your /etc/hosts
file. This must be done as root
, so at the Terminal
, type in "sudo vi /etc/hosts
". This will ask for your password...
Add the hostname you noted from earlier at the end of lines that start with "127.0.0.1
" and "::1
". If you don't know how to use vi
, look here
. You can also use nano
instead, just replace "vi
" in the command above with "nano
In the end this is what my /etc/hosts
file looked like:
After making this change, I noticed that SoapUI
took 5 seconds
to start, before it was taking 21 seconds
. Also SQL Developer
was now taking just 3 seconds
to connect to a database, versus 21 seconds
prior to this change.
