Unchecked exception thrown when an attempt is made to initiate an accept operation on a channel and a previous accept operation has not completed.

Unchecked exception thrown when an attempt is made to bind the socket a network oriented channel that is already bound.

Unchecked exception thrown when an attempt is made to connect a SocketChannel that is already connected.

Checked exception received by a thread when another thread closes the channel or the part of the channel upon which it is blocked in an I/O operation.

Unchecked exception thrown when an attempt is made to use a selection key that is no longer valid.

Checked exception received by a thread when another thread interrupts it while it is blocked in an I/O operation upon a channel.

Checked exception thrown when an attempt is made to invoke or complete an I/O operation upon channel that is closed, or at least closed to that operation.

Unchecked exception thrown when an attempt is made to invoke an I/O operation upon a closed selector.

Unchecked exception thrown when an attempt is made to connect a SocketChannel for which a non-blocking connection operation is already in progress.

Checked exception received by a thread when another thread interrupts it while it is waiting to acquire a file lock.

Unchecked exception thrown when a blocking-mode-specific operation is invoked upon a channel in the incorrect blocking mode.

Unchecked exception thrown when an attempt is made to open a channel in a group that was not created by the same provider.

Unchecked exception thrown when an attempt is made to invoke an I/O operation upon a socket channel that is not yet connected.

Unchecked exception thrown when an attempt is made to acquire a lock on a region of a file that overlaps a region already locked by the same Java virtual machine, or when another thread is already waiting to lock an overlapping region of the same file.

Unchecked exception thrown when an attempt is made to read from an asynchronous socket channel and a previous read has not completed.

Unchecked exception thrown when an attempt is made to construct a channel in a group that is shutdown or the completion handler for an I/O operation cannot be invoked because the channel group has terminated.

Unchecked exception thrown when an attempt is made to invoke a network operation upon an unresolved socket address.

Unchecked exception thrown when an attempt is made to bind or connect to a socket address of a type that is not supported.

Unchecked exception thrown when an attempt is made to write to an asynchronous socket channel and a previous write has not completed.
