   Removing the `head -1` means multiple lines will pass through - so if `java -version` changed to something along these lines we'd get a multi-line value back:
   
   ```
   openjdk version "1.8.0_362"
   OpenJDK Runtime Environment (build 1.8.0_362-b09)
   OpenJDK 64-Bit Server VM (build 25.362-b09, mixed mode)
   SomeOS version "1.42.5"
   ```
   
   Keeping the `head -1` (after the `grep`) would protect against this - so I think that's worth putting back in.
