## Package com.sun.jdi

This is the core package of the Java Debug Interface (JDI), it defines mirrors for values, types, and the target VirtualMachine itself - as well bootstrapping facilities.

InvalidTypeException | Thrown to indicate a type mismatch in setting the value of a field or variable.
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.

## Package com.sun.jdi Description

This is the core package of the Java Debug 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`.

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.
