Well, this happens to be a problem with the JVM version.
Known versions with this problem:

1.7.0 update 55
1.7.0 update 65
1.7.0 update 67
1.8.0 update 11

Solution:

Edit the start.bat and add JVM argument "-noverify" to have the code working.

The default JVM options look like this:

::* default JVM options
if not defined CQ_JVM_OPTS set CQ_JVM_OPTS=-Xmx2048m -XX:MaxPermSize=512M -noverify -Djava.awt.headless=true

Hope this helped!
