[hibernate-issues] [Hibernate-JIRA] Commented: (ANN-423) @Min broken with BigInteger/BigDecimal

Dan Armak commented on ANN-423:
-------------------------------

Oh, and for String-typed properties, the value should be parsed using a BigDecimal and not a Double (in e.g. MinValidator:29) to support arbitrary value sizes. I have to go now, but can provide a trivial patch for this tomorrow if you wish.

> MinValidator supports properties of type BigInteger and BigDecimal by coding against Number.longValue(). However, in BigInteger and BigDecimal, longValue() returns the lower 64 bits, which can flip the apparent sign for a BigInteger > Long.MAX_VALUE or < Long.MIN_VALUE. In these cases, @Min or @Max validation (respectively) will fail.
