I run Eclipse and
Java on my MacBook Pro. 2 days ago I installed the latest JDK on my machine and noticed that the whole application became very sluggish. Further tests seem to indicate that any network comms, including the TCP/IP socket connection between
jdbc and mysql are experiencing serious delays. I read the release notes for the latest JDK and there were some passing references to DNS. This only seems to effect my app on OS X, I've tried Windows and it does not seem to occur.
The following
InetAddress.getLocalHost().getHostName()
takes much longer on my Mac with 1.8.0.60 than it does with the previous version.
So - how do I revert the default JDK on my Mac to the previous version. Re-installing the older JDK does not seem to help and nothing in the Java control panel appears to let you select the default. I'm assuming I need to do something at the Command prompt.
Any advice on how to back out the current JDK would be great, also any confirmation of this problem with this version on a OS X machine would be re-assuring. I found mySQL database io particularly noticeable.
