https://github.com/apache/drill/pull/1182
There are two issues with enabling `apache-release` by default:
- it triggers creating source `apache-drill-...-src.tar.gz` and
`apache-drill-...-src.zip` archives.
- maven build for any sub-module fails.
The change disables activation of the `apache-release` profile based on JDK
version and requires explicit activation during the Apache release process.
JDK 1.7 is not supported. See DRILL-1491 and #1143.---
