I am having a challenge. I am using Jpos and I am trying to set field 127 sub-element 033 as well as unpacking it. When packing, seems like its working fine but when trying to unpack I get the following exception.
Caused by: org.jpos.iso.ISOException: org.jpos.iso.IFA_LLCHAR: Problem unpacking field 11 (java.lang.NegativeArraySizeException) unpacking field=127, consumed=287
If i comment out the setting of field 127.033 as well as removing the isofield with id = 33 under field 127 in fields.xml everything works well. But when i uncomment the above, the error re-surfaces.
