Details:

When configure tries to check the version of Java found to see if it is new
enough, the string parsing fails on OpenJDK 10 and 11 on Debian unstable:


$ /usr/lib/jvm/java-9-openjdk-amd64/bin/java -version
openjdk version "9.0.4"
OpenJDK Runtime Environment (build 9.0.4+12-Debian-2)
OpenJDK 64-Bit Server VM (build 9.0.4+12-Debian-2, mixed mode)
$ /usr/lib/jvm/java-10-openjdk-amd64/bin/java -version
openjdk version "10" 2018-03-20
OpenJDK Runtime Environment (build 10+46-Debian-2)
OpenJDK 64-Bit Server VM (build 10+46-Debian-2, mixed mode)
$ /usr/lib/jvm/java-11-openjdk-amd64/bin/java -version
openjdk version "11" 2018-09-18
OpenJDK Runtime Environment (build 11+5-Debian-1)
OpenJDK 64-Bit Server VM (build 11+5-Debian-1, mixed mode)


Two differences from what configure expects
* There is only a single number, not major.minor
* There is additional text after the closing quote that the sed command
doesn't delete
