I saw that the most recent openjdk version is openjdk-21. I installed it and immediately afterwards installed Maven at which point the installation processes indicated that openjdk-17 must also be co-installed, apparently, so Maven can work. I proceeded and indeed in my jvm folder I now see 2 java versions.

Would someone please explain what is going on with this curious installation? Why can't Maven work solely off of Java-21/openjdk-21? Will having two versions of Java evetually confuse Termux? I manually indicated in the .bashrc file for the JAVA_HOME variable to point to openjdk-21, but I'm still contused as why Maven appears to be tethered to Java-17 and doesn't just use Java-21. Having two versions of Java also makes me concerned about taking up more memory on the device too.
