I'd start by adding a logger to your packager:

Logger logger = new Logger();

logger.addListener (new SimpleLogListener(System.out));

((LogSource)p).setLogger(logger, "debug");

Then run again and see if fields prior to 59 get properly unpacked.

I know I am missing something here but don't know what is going wrong with field 59.
I am giving complete xml file because I this there might be something wrong with fields other than 59th.

Any help would be appreciated.

The field length looks odd, so it is likely to be as issue in the lead
up to the field that tries to run off the end.

There is likely a mismatch between packager and message.

I suggest you add a Logger to you Packager:-

.
.

Logger logger = new Logger();
logger.addListener (new SimpleLogListener (System.out));

p.setLogger(logger)
.
.

then you will see on your stdout (or existing log if you have a Logger
to reuse) what data is going into which fields and thus what is causing
the misalignment in your test - bad data or bad packager.

:) p was an ISOPackager, not a GenericPackager (which implements LogSource)
