I've got two "slots" of java currently installed (8 and 11). I see how one uses "eselect java" to contol which one is invoked by /usr/bin/java.
How does one manually invoke non-selected version(s) of java? For other slotted things like gcc and python, you can use pythonX.Y or gcc-X.Y.Z to invoke the non-selected version. What's the equivalent for java? -- Grant
