You are executing your GlassFish with 1.7.0_02 - but maybe you compiled it with a JDK 8?

You can execute older java classes in newer JREs, but not the other way round. So just install a recent JRE or explicitely start you GlassFish (or the IDE it is running in) with the JDK you use for compiling your code.
