Arch Linux

Description: I think icedtea-web dropped support for jdk7, but the package still lists compatibility with both jdk7 and jdk8:
java-runtime-openjdk (jre7-openjdk, jre8-openjdk, jre10-openjdk, jre-openjdk)


Additional info:
$ java -version
java version "1.7.0_171"
OpenJDK Runtime Environment (IcedTea 2.6.13) (Arch Linux build 7.u171_2.6.13-1-x86_64)
OpenJDK 64-Bit Server VM (build 24.171-b02, mixed mode)
$ archlinux-java status
Available Java environments:
java-7-openjdk (default)

Package versions:
* icedtea-web 1.7-1
* jre7-openjdk-headless 7.u171_2.6.13-1
* jre7-openjdk 7.u171_2.6.13-1


Steps to reproduce:
# Set java-7-openjdk as the system java
# install icedtea-web
# attempting to use javaws to launch a jnlp results in
```

When I searched for this error, I found others fixed it on various distros by changing the system java to java8. I think this means upstream dropped support and the package should just be updated to remove java7 as a valid dependency.
