      public IllegalStateException(String message, Throwable cause)
      Constructs a new exception with the specified detail message and cause.

      Note that the detail message associated with cause is not automatically incorporated in this exception's detail message.

      Parameters:
      message - the detail message (which is saved for later retrieval by the Throwable.getMessage() method).
      cause - the cause (which is saved for later retrieval by the Throwable.getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)

    • IllegalStateException

      public IllegalStateException(Throwable cause)
      Constructs a new exception with the specified cause and a detail message of (cause==null ? null : cause.toString()) (which typically contains the class and detail message of cause). This constructor is useful for exceptions that are little more than wrappers for other throwables (for example, PrivilegedActionException).
      Parameters:
      cause - the cause (which is saved for later retrieval by the Throwable.getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)
