When copying a guided rule that contains a BigDecimal field, it adds another letter "B" in the drools file.

Initial file:

package com.myspace.reproducer_02415008;

import java.lang.Number;

rule "GuidedRule"
dialect "mvel"
when
DataObject( field == 0.0B )
then
end

--------

Copied file source result code. Note the two B's :

package com.myspace.reproducer_02415008;

import java.lang.Number;

rule "teste"
dialect "mvel"
when
DataObject( field == 0.0BB )
then
end
