Sec 2.16.4 states that InternalError may be delivered asynchronously, but does not make this claim for any other of the subclasses of VirtualMachineError. But sec 6.3 mentions that any subclass of VirtualMachineError may be thrown at any time during the operation of the JVM. So are all subclasses of VME asynchronous? And if not, what is the difference between InternalError being raised asynchronously and OutOfMemoryError being raised at any time?

And if not, what is the difference between InternalError being raised asynchronously and OutOfMemoryError being raised at any time? My understanding is that 'throw at any time' means throwing at any moment if error happened at this very moment. For example, you can throw OOME at any bytecode which allocates memory directly or indirectly - but you have to throw it before next bytecode is executed. On the other hand, asynchronous throw can happen at any point in the future, possibly even in different thread, from place which triggered the error itself. It is just my idea how to interpret that - I'm in no way expert on the subject.
