Description rlee CLA 2010-07-06 13:04:53 EDT 
Build Identifier: 2.1.0

When org.eclipse.persistence.internal.helper.compareBigDecimals is called the values are cast to a double if the scales are not identical and then compared.  This is kills the precision causing a false positive if the number is large as the double casting causes the value to lose precision.

Reproducible: Always

Steps to Reproduce:
1. Send value one as 12345678901234567890123456789012345
2. Send value two as 12345678901234567890123456789012300
3. Result is that the values are equal and this is not true
