Answer 2

I had the same problem, until I installed the JDK 1.8.0_60. That's right, installing the latest JDK helped!

After you install the latest JDK, change the settings on the Eclipse There are two steps to the process:

1. Select the appropriate JRE in Eclipse > Preferences > Java > Installed JREs as shown here:

   2. In Project > Properties > Java Build Path, Add Library as depicted below:

Answer 3

I got the same problem on Eclipse (MacOSX Yosemite) this morning but yesterday everything worked... To solve the problem I just deselected the checkbox for another JDK in Project > Properties > Java Build Path restarted Eclipse, reselected the good one (JDK 1.8.0_60), restarted Eclipse again and voilà ! Just a weird bug with checkboxes...

Hope it ll help you.
