The registration process places the registered VM in the Java VM wrapper configuration file in sorted order. When unregistering the Java VM is removed from the Java VM wrapper configuration file and will no longer be a possible choice for .Nm javavm . .Sh FILES .Bl -tag -width indent .It Pa %%PREFIX%%/etc/javavms The location of the Java VM wrapper configuration file. .El .Sh EXAMPLES .Bl -tag -width indent .It %%PREFIX%%/bin/registervm %%LOCALBASE%%/openjdk11/bin/java Register %%LOCALBASE%%/openjdk11/bin/java as a possible choice of Java VM for .Nm javavm . .It %%PREFIX%%/bin/unregistervm %%LOCALBASE%%/openjdk11/bin/java Remove %%LOCALBASE%%/openjdk11/bin/java as a possible choice of Java VM for .Nm javavm . .El .Sh SEE ALSO .Xr checkvms 1 , .Xr javavm 1 , .Xr javavms 5 .Sh BUGS The .Nm and .Nm unregistervm utilities remove both blank lines and purely comment lines from the Java VM wrapper configuration file.
