Module jdk.jdi

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. 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.

  • Exception Summary 
    Exception Description
    AbsentInformationException
    Thrown to indicate line number or variable information is not available.
    ClassNotLoadedException
    Thrown to indicate that the requested class has not yet been loaded through the appropriate class loader.
    ClassNotPreparedException
    Thrown to indicate that the requested operation cannot be completed because the specified class has not yet been prepared.
    IncompatibleThreadStateException
    Thrown to indicate that the requested operation cannot be completed while the specified thread is in its current state.
    InconsistentDebugInfoException
    Thrown to indicate that there is an inconistency in the debug information provided by the target VM.
    InternalException
    Thrown to indicate that an unexpected internal error has occurred.
    InvalidCodeIndexException Deprecated.
    This exception is no longer thrown
    InvalidLineNumberException Deprecated.
    This exception is no longer thrown
    InvalidModuleException
    Thrown to indicate that the requested module is invalid or became invalid after the module was unloaded.
    InvalidStackFrameException
    Thrown to indicate that the requested operation cannot be completed because the specified stack frame is no longer valid.
