When parsing my library file (from iTunes 11.0.2), I encounter the following:

Caused by: org.kafsemo.titl.UnknownHohmException: Unknown type: 509 (0x1FD)
Hex: 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x01 0x00 0x00 0x00 0x08 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x31 0x00 0x32 0x00 0x33 0x00 0x34

I then add 0x1FD as a case before line 368, just to eat the unknown type and get the same problem again:

Caused by: org.kafsemo.titl.UnknownHohmException: Unknown type: 510 (0x1FE)

If I add that case too, it goes worse:
