getHeader() and getTrailer() not behaving correctly

Hi,
Don't know if this a bug or we are not using the API correctly.
But since 2.1.0 we observe strange behavior concering the checksum and bodylength field.

JUnit Test:

@Test
public void testBodyLengthAndChecksum() throws FieldNotFound

{ TradeCaptureReport tradeCaptureReport = new TradeCaptureReport(); tradeCaptureReport.set(new Instrument(new Symbol("[N/A]"))); System.out.println(tradeCaptureReport.toString()); Header header = tradeCaptureReport.getHeader(); System.out.println(header.getString(9)); Trailer trailer = tradeCaptureReport.getTrailer(); System.out.println(trailer.getString(10)); }

2.0.0 ====>>>

8=FIX.4.49=1535=AE55=[N/A]10=072
15
072

2.1.0 ====>>>

8=FIX.4.49=1535=AE55=[N/A]10=072
100
000

Any help would be much appreciated.

Greetings,
Simon.
