Classe Money e Percent - Erro ao Salvar

Boa noite, amigos.

Estou com um problema que realmente não consigo resolver e preciso da ajuda de vocês.

Criei a classe "Money" e "Percent" que nada mais é que a cópia do "Double" (java), apenas alterando o toString() para um retorno mais amigável, além de separar melhor as atribuições.

Mapeei o GORM e ele tá usando o tipo certo no BD (double), porém, ao tentar salvar dá a seguinte exceção:

Adicionei o método toDouble() como tentativa, sem sucesso.

* floating-point arithmetic, which includes preserving the sign of a zero
* value.
*
* Note that the round-to-nearest rule also implies overflow and underflow
* behaviour; if the exact value of {@code s} is large enough in magnitude
* (greater than or equal to ({@link

* {@code double} will result in an infinity and if the exact value of
* {@code s} is small enough in magnitude (less than or equal to
* {@link #MIN_VALUE}/2), rounding to float will result in a zero.
*
* Finally, after rounding a {@code AsgardDouble} object representing this
* {@code double} value is returned.

* <p> To interpret localized string representations of a floating-point

*
* <p>Note that trailing format specifiers, specifiers that determine the
* type of a floating-point literal ({@code 1.0f} is a {@code float} value;
* {@code 1.0d} is a {@code double} value), do <em>not</em> influence the
* results of this method. In other words, the numerical value of the input
* string is converted directly to the target floating-point type. The
* two-step sequence of conversions, string to {@code float} followed by
* {@code float} to {@code double}, is <em>not</em> equivalent to converting
* a string directly to {@code double}. For example, the {@code float}
* literal {@code 0.1f} is equal to the {@code double} value
* {@code 0.10000000149011612}; the {@code float} literal {@code 0.1f}
* represents a different numerical value than the {@code double} literal
* {@code 0.1}. (The numerical value 0.1 cannot be exactly represented in a
* binary floating-point number.)
*
* <p>To avoid calling this method on an invalid string and having a
* {@code NumberFormatException} be thrown, the regular expression below can
* be used to screen the input string:
*
* <code>
* <pre>
* final String Digits = "(\p{Digit}+)";
* final String HexDigits = "(\p{XDigit}+)";
* // an exponent is 'e' or 'E' followed by an optionally

* // A decimal floating-point string representing a finite positive

* the {@code AsgardDouble.doubleToRawLongBits} method.
*
* <p>In all other cases, let <i>s</i>, <i>e</i>, and <i>m</i> be three

*
* <p>Note that this method may not be able to return a {@code double} NaN
* with exactly same bit pattern as the {@code long} argument. IEEE 754
* distinguishes between two kinds of NaNs, quiet NaNs and <i>signaling
* NaNs</i>. The differences between the two kinds of NaN are generally not
* visible in Java. Arithmetic operations on signaling NaNs turn them into
* quiet NaNs with a different, but often similar, bit pattern. However, on
* some processors merely copying a signaling NaN also performs that
* conversion. In particular, copying a signaling NaN to return it to the
* calling method may perform this conversion. So {@code longBitsToDouble}
* may not be able to return a {@code double} with a signaling NaN bit
* pattern. Consequently, for some {@code long} values,
* {@code doubleToRawLongBits(longBitsToDouble(start))} may <i>not</i> equal
* {@code start}. Moreover, which particular bit patterns represent
* signaling NaNs is platform dependent; although all NaN bit patterns,
* quiet or signaling, must be in the NaN range identified above.
