Thomas Mueller commented on JCR-3652:
-------------------------------------
One potential code path is: NodeStateEx.setPropertyValues. When updating an
existing property, the type and values array is set, but the "multiple" flag is
ignored. So it seems to be possible to set the property values to an empty
array, for an existing, non-multi-valued property state. The question is, when
and why is this method called for the property isCheckedOut with an empty
values array.

> 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.
