getString on BIT(1) field doesn't respect transformedBitIsBoolean option

resultset on BIT field normally return value like b'1011'.
Option transformedBitIsBoolean permit for BIT(1) value to return Boolean value by default.
This is not the case when using resultset.getString.

this result in returning b'0' or b'1' in place of false/true for BIT(1) when transformedBitIsBoolean is set (default)
