Whenever I try to connect to a database using Java 7, SQuirrel SQL 3.4.0 freezes (it means the application stops responding at all, including menus).

I was trying MySQL driver (5.1.26, thread dump attached), Vertica driver and a simple custom driver, with no success. Everything works fine with Java 6.

Full java details follow:

works with:
java version "1.6.0_65"
Java(TM) SE Runtime Environment (build 1.6.0_65-b14-462-11M4609)
Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-462, mixed mode)

freezes with:
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)

Thanks
