I have empty ITL file from iTunes 12.2 Mac OS X, but library can't handle it: java.io.IOException: Expected zero for inline HPtoDFM length (was 125521) at org.kafsemo.titl.Hdfm.readInline(Hdfm.java:131) at org.kafsemo.titl.ParseLibrary.drain(ParseLibrary.java:500) at org.kafsemo.titl.ParseLibrary.parse(ParseLibrary.java:94) at org.kafsemo.titl.ParseLibrary.parse(ParseLibrary.java:80)

Same problem with a large iTunes itl: Exception in thread "main" java.io.IOException: Expected zero for inline HDFM length (was 84258304) at org.kafsemo.titl.Hdfm.readInline(Hdfm.java:131) at org.kafsemo.titl.ParseLibrary.drain(ParseLibrary.java:500) at org.kafsemo.titl.ParseLibrary.parse(ParseLibrary.java:94) at org.kafsemo.titl.ParseLibrary.parse(ParseLibrary.java:80) at org.kafsemo.titl.tools.ExportRatings.main(ExportRatings.java:44)

I have debugged this and think I have a idea whats going on. It does the following steps: 1 - Reads the first hdfm record (144 bytes) 2 - Decrypts and decompresses the remainder of the file --- File Length set to 4403636 3 - Reads a hdsm record (96 bytes) --- Remaining length 4403540 4 - Identifies a hdfm record (144 byte) the code expects the second integer to be zero but it gets 4403780 which seems to be the total deflated file length plus 144 for the initial hdfm record.

I can get past this but then things get out of sync later on :(

Same here. Anyone got through that?
