无法使用JPOS支持ISO 8583 F137

Question

我正在尝试将F137引入我的ISO 8583处理中。在打包和解压缩f137的ISO消息时，我使用了以下xml配置。

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

我可以将F137打包在外发消息中可以看到F137的位置，

，但是在解压jpos期间会引发以下异常。

<session-error>
    <iso-exception>
      org.jpos.iso.IFB_LLHNUM: Problem unpacking field 32 (org.jpos.iso.ISOException: Field length 96 too long. Max: 11) unpacking field=32, consumed=54

JPOS支持的字段是否大于F128。 Btw应用程序无需F137即可正常运行。
