Usage of BigDecial.toString() in Marshaller inconsistent when switching from Java 1.4 (and below) to Java 5.0 (and above)

Apparently, Sun decided to change the semantics of BigDecimal.toString() with the release of Java 5.0, allowing scientific notation to be 'produced' when calculating the String representation of a BigDecimal instance. With Java 5.0, BigDecimal.toString() can return a String in scientific notation. As we use a BigDecimal for the XML schema type <xs:decimal>, this is illegal (as per XML schema specification, this is not allowed).

As a result of this, BigDecimal.toPlainString() should be used for Java 5.0 and above (ideally for BigDecimals representing ,xs>decimal> only). It looks like the code in question (within Marshaller) will have to take into account the JVM release number to make an educated decision.
