community/java-common: fix links to jdk executables
Running javac
with openjdk8 results in command not found
as the symbolic link at /usr/bin/javac
points to an invalid location. Using openjdk9+ was fine though.
This MR changes the link target for all java executable from /usr/lib/jvm/default-jvm/jre/bin
to /usr/lib/jvm/default-jvm/bin
.
