InvocationException | Thrown to indicate an exception occurred in an invoked method within the target VM.
NativeMethodException | Thrown to indicate an operation cannot be completed because it is not valid for a native method.
ObjectCollectedException | Thrown to indicate that the requested operation cannot be completed because the specified object has been garbage collected.
VMDisconnectedException | Unchecked exception thrown to indicate that the requested operation cannot be completed because there is no longer a connection to the target VM.
VMMismatchException | Thrown to indicate that the requested operation cannot be completed because the a mirror from one target VM is being combined with a mirror from another target VM.
VMOutOfMemoryException | Thrown to indicate that the requested operation cannot be completed because the target VM has run out of memory.

## Package com.sun.jdi Description

This is the core package of the Java Debugging Interface (JDI), it defines mirrors for values, types, and the target VirtualMachine itself - as well bootstrapping facilities. `VirtualMachine` mirrors the target virtual machine and is the origin of all information provided by the JDI. A VirtualMachine is typically created by using the `VirtualMachineManager` to create a connection to the target virtual machine (see the com.sun.jdi.connect package). In turn the `VirtualMachineManager` is typically created by calling `Bootstrap.virtualMachineManager()`.

Most of the methods within this package can throw the unchecked exception `VMDisconnectedException`. This will be documented with more specificity in future releases.

Methods may be added to the interfaces in the JDI packages in future releases. Existing packages may be renamed if the JDI becomes a standard extension.
