looks like jackson-jr does not support reading null date as it always expects a long value.
see comment here FasterXML/jackson-jr#48 (comment)
drawback of using a jr json library. JsonFormat annotation does not work too since jackson-jr supports only a subset of jackson-annotations, which does not include JsonFormat.

[jbartok]

Problem will be fixed by #2247 via documenting how to work around it (it's unlikely that jackson-jr will fix it, since it's there since 4 years).

[jbartok]

For now the workaround from #2247 should be fine, we are going to get a proper fix from jackson-jr for 4.3.

I've submitted an issue, let's see what feedback we get: FasterXML/jackson-jr#73

[jbartok]

Has been fixed by #2459.
