The untethered version of CodeInfo, which can be released by the GC at ANY safepoint. Before it is possible to access any data, it is necessary to convert a pointer of this type to a CodeInfo pointer using CodeInfoAccess.acquireTether and CodeInfoAccess.convert. For more details, refer to the documentation of CodeInfoAccess. 

NEVER do a direct cast from UntetheredCodeInfo to CodeInfo. 
 If it is necessary to access data without acquiring the tether, then call the static methods of the class UntetheredCodeInfoAccess from uninterruptible code. /**
