Error when starting IDE 1.6.7 when network connection is lost

Development Tools IDE 1.x

When starting IDE 1.6.7 on Mac OS X Yosemite (10.10.5) and the network connection is lost during starting of the IDE, a Java error is shown if the IDE is started by opening a sketch from the Finder. The sketch is stored on the local disk. After recovery of the network connection, all works fine.

Just to let you know. Not a big deal.

Your losing network connection that frequently?

Sounds like you need to check your router.

Sounds like you need to check your router.

Because nobody ever does work while in a plane, train, hotel, using a mobile connection, or otherwise not having reliable connectivity. ::slight_smile:

The IDE should not crash when deprived of a network connection. I and many others routinely write code without an internet connection. Sometimes even intentionally to get rid of the distraction.
