Loosen option constraint for Java version

Later versions of 1.8.0 include options beyond ea. Example:

```
⫸  docker run -t java:8-jdk-alpine java -version
openjdk version "1.8.0_111-internal"
OpenJDK Runtime Environment (build 1.8.0_111-internal-alpine-r0-b14)
OpenJDK 64-Bit Server VM (build 25.111-b14, mixed mode)
```
