How can I install an additional java on MacOS? I installed jdk8 and that works fine. But now I need a jdk7 installation for development purposes. When trying to install the old version via DMG file, i get a warning, that there is already a newer version of java installed and the installer quits.
/usr/libexec/java_home -verbose Matching Java Virtual Machines (1): 1.8.0_20, x86_64: "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_20.jdk/Contents/Home /Library/Java/JavaVirtualMachines/jdk1.8.0_20.jdk/Contents/Home
How to install jdk7 in addition to this one?
