Regression: error decoding metadata from some m4a files in 0.8.6

[mvmn]

I've tried to play some m4a files I've bought from iTunes store, and everything worked with version 0.8.5 from Maven. But when I started to work with current code from master - MP4Container creation failed with this error:

Exception in thread "main" java.io.IOException: error while decoding box '����' at offset 73633: box too large for parent

Checking differences between 0.8.5 and 0.8.6 I've found this change:

When commented out, decoding works again.

I'm sorry I can't provide more relevant data and can't attach m4a file (because that'd be a copyright violation). If needed I suppose though I could provide some portion of the file content, e.g. where headers are.
