> I have got a strange case where some node bundle is broken, seemingly because 
> a byte is missing. I can't explain the missing byte, but it is reproducible, 
> meaning that writing the bundles again will break them again. There are 11 
> broken bundles, 10 of them have the size 480 bytes and one is slightly 
> larger. It is always a boolean property value that is missing, always the 
> value for the property jcr:isCheckedOut.
> As a (temporary) solution, and to help analyze what the problem might be, I 
> will create a patch that does the following:
> * When serializing a bundle, check if the byte array can be de-serialized. If 
> not, then try again. Starting with the 3th try, use a slower variant where 
> before and after writing the boolean value the buffer is flushed. I'm aware 
> that ByteArrayOutputStream.flush doesn't do much, but maybe it solves the 
> problem (let's see) if the problem is related to a JVM issue.
> * If de-serializing a bundle fails, check if it's because of a missing 
> boolean property value. If yes, insert the missing byte.
> I have also added some log messages (warning / error) to help analyze the 
> problem.
