I’m not a Java developer but I can see internally where I’m working that some changes are already happening at the Java teams after Oracle took control of Java.
Development is done mainly in Eclipse, but now a plan is in place to move to JBuilder. Some how Oracle SOA suit is coming into the picture and it is nicely integrated using Java.
As a non Java developer just looking from the fence it seems that Java will stay for a while, but Enterprises will start looking for options.
