We need to match to the end of the line to make it work with Java 10 as explained in the expanded comment.
Tested manually for all supported versions:
```shell
echo $(.../jdk1.8.0_152.jdk/Contents/Home/bin/java -version 2>&1 | sed -E -n 's/.* version "([0-9]*).*$/\1/p')
1
echo $(.../jdk-9.0.4.jdk/Contents/Home/bin/java -version 2>&1 | sed -E -n 's/.* version "([0-9]*).*$/\1/p')
9
echo $(.../jdk-10.jdk/Contents/Home/bin/java -version 2>&1 | sed -E -n 's/.* version "([0-9]*).*$/\1/p')
10
echo $(.../jdk-10.0.1.jdk/Contents/Home/bin/java -version 2>&1 | sed -E -n 's/.* version "([0-9]*).*$/\1/p')
10
