[keycloak-user] ZipException: Unsupported compression method

[Juraci Paixão Kröhling]

We are seeing this exception "from time to time" on the logs. 
Unfortunately, I don't have much information about it, as I couldn't 
reproduce it consistently (yet), but perhaps someone has also seen this 
before? We are using KC 1.8.0.CR1.
