Currently I'm using Java jdk 1.6.0_26 for my ecli开发者_Python百科pse based application. As now Java 7 is available, could I directly switch to Java 7 from Java 6?

If yes, what would be the impacts of it? If no, what are all the things should I look into so that I can switch to Java 7?

Thanks in advance!

Java7 is awesome and everything, but do not switch to Java7 just yet. JIT compiler issue with the HotSpot VM of Java 7 which will be patched in Update2.

The Java 7 issues are only for quite rare circumstances and are easily disabled.

I've run Eclipse with Java 7 Developers Preview since it came out and never seen any problems.

You should at least try to see if it works well for you.
