FULL PRODUCT VERSION :
A DESCRIPTION OF THE PROBLEM :
We have a critical issue with latest release of JRE (1.8.0_40) and Mac OS 10.10, aka Yosemite.
Our swing application is unusable because all text fields don't get focus when we click on it.
This issue is easily reproducible with swing code examples, hosted on oracle website at http://docs.oracle.com/javase/tutorial/uiswing/examples/misc/index.html.
You can try to run InputVerificationDemo project for example.
We get the same issue with the current early access release of JDK8 (8u60 Build b05).
This bug can be reproduced always.
