> Support for can_tag_objects capability is incorrect.
> A. the following actions produce an error result:
>   1. can_tag_objects capability was possessed by AddCapabilities() function 
>   2. an_tag_objects capability was released by RelinquishCapabilities()
>   3. Attempt to possess this capability again with AddCapabilities() function produces JVMTI_ERROR_NOT_AVAILABLE
> B. in current implementation can_tag_objects capability can by possessed only by one jvmti environment. 
>   GetPotentialCapabilities() reports that this capability is available even if it already possessed by other agent and can't be possessed by this agent.
