      java.lang.Throwable
          java.lang.Exception
              java.io.IOException

    @TransactionType(value=NOT_SUPPORTED)
    public class UTFDataFormatException

extends IOException

Signals that a malformed UTF-8 string has been read in a data input stream or by any class that implements the data input interface. See the `writeUTF` method for the format in which UTF-8 strings are read and written.

Direct instances of this exception class are not bound to any context and can be passed between contexts without any restrictions. Objects created and returned by the methods of this class are owned by the caller. In particular, a call to the `Throwable.getMessage()` returns a String instance bound to the owner context of the caller.

See Runtime Environment Specification for the Java Card Platform, Connected Edition, chapter 7 for details regarding transfer of ownership.

  JDK1.0, CLDC 1.0, Java Card 3.0
