To open “this Java application” you need to install the legacy Java SE 6 runtime.

I'm using Mac and I have Java 1.8.0_144 installed.

Is my java version supported?

$ /usr/libexec/java_home  -V

No Java runtime present, requesting install.

Also a popup window appears:

Should it work with Java 8?

Just found this workaround and it works:

This issue was solved by adding JNI to JVMCapabilities in /Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Info.plist as suggested in joeferner/node-java#90.
