I'm kind of new in java, so probably my question is too obvious. The other day looking into /usr/lib/jvm/java-1.8.0-openjdk-188.8.131.52-3.b17.fc21.x86_64 in my Fedora, I notice some duplicated binaries like bin/java and jre/bin/java.
I read about the difference between JRE and JDK, but I don't get why is necessary to keep both binaries if we only use one of them.
Hope you can help me to understand a little more.
Thanks a lot.
