¿How to configure correctly Spark?, please Help me!

I'm trying to make the Spark allows chat with other members to my company without make troubles and block the program, but some contacts are blocking the spark when I try to chat them.

¿Which Java is recommended to Spark?, I had uninstalled the early Java version and I think that Java is the problem.

Akways since I use the program this remains with error In the log file:

Please help me!
