Unable to upack ISO 8583 F137 using JPOS

I'm trying to introduce F137 to my ISO 8583 processing. I'm using following xml configurations in packing and unpacking the ISO message for f137.

<isofield
id="137"
length="2"
name="Application Transaction Counter"
class="org.jpos.iso.IFB_BINARY"/>

I'm able to pack the F137 where I'm able to see F137 in outgoing message, 

<send>
    <isomsg direction="outgoing">

    </isomsg>
  </send>

but during unpacking jpos throws following exception.

    <iso-exception>

Does JPOS support fields greater than F128. Btw Application works properly without F137.

ISO-8583 defines 128 fields. Systems that use fields beyond 128 are quite unusual, and weird (I see this sample message seems to come from Bhutan). That said, jPOS supports them. I suggest you search the jPOS forum for the keyword 'tertiary bitmap':
