Examples of AttachNotSupportedException

com.sun.tools.attach.AttachNotSupportedException
Thrown by {@link VirtualMachine#attach VirtalMachine.attach} when attempting to attach to a Javavirtual machine for which a compatible {@link com.sun.tools.attach.spi.AttachProvider AttachProvider} does not exist. It is also thrown by {@link com.sun.tools.attach.spi.AttachProvider#attachVirtualMachine AttachProvider.attachVirtualMachine} if the provider attempts toattach to a Java virtual machine with which it not compatible.
