/**
* Indicates if a class is recompilable. Recompilable means, that the classloader will try to
* locate a groovy source file for this class and then compile it again, adding the resulting
* class as entry to the cache. Giving null as class is like a recompilation, so the method should
* always return true here. Only classes that are implementing GroovyObject are compilable and
* only if the timestamp in the class is lower than Long.MAX_VALUE.
*
* <p>NOTE: First the parent loaders will be asked and only if they don't return a class the
* recompilation will happen. Recompilation also only happen if the source file is newer.
*
* @param cls the class to be tested. If null the method should return true
* @return true if the class should be compiled again
* @see #isSourceNewer(URL, Class)
