Flink Jira Bot updated FLINK-7614:
----------------------------------
    Labels: auto-deprioritized-major stale-minor  (was: 
auto-deprioritized-major)

I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help 
the community manage its development. I see this issues has been marked as 
Minor but is unassigned and neither itself nor its Sub-Tasks have been updated 
for 180 days. I have gone ahead and marked it "stale-minor". If this ticket is 
still Minor, please either assign yourself or give an update. Afterwards, 
please remove the label or in 7 days the issue will be deprioritized.

> A user was struggling with working with POJO types, as reported in 
> http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Exception-when-using-keyby-operator-td15435.html
> We seem to have similar "accidentally not valid POJO" problems every now and 
> then from users. We can probably improve this by having a solid code snippet 
> of a valid POJO under [1] that demonstrates the POJO rules, instead of just a 
> text description of the rules. A guideline to check if your type is actually 
> recognized as a POJO by Flink should also be included.
