> Currently ConditionallyAvailable configured object implementations declared with annotation _ManagedObjectFactoryConstructor#conditionallyAvailable_ are required to have static method _isAvaialble()_ on configured object implementation class. If implementation class have compile time dependencies to external classes which might not be present on classpath, the loading of class for such implementation fails with ClassDefNotFoundError when calling static method Impl#isAvailable() from factory. Thus, in order to have working Impl#isAvailable(), the implementation should not be linked with classes which might not be available when call to check is made.
> Alternatively, we can implement a condition expression in _ManagedObjectFactoryConstructor_ which can be evaluated as part of _ConditionallyAvailable#isAvaialble()_ call. That would allow to relax the requirements to implementation class dependencies by having a separate class with static method for availability evaluation which will not have issues with class loading due to not being linked with not available classes
