Eliminate a finalize() method in the Swing macOS implementation.
I tested that the dispose method is being called by running this small test in
combination with some 'println' statements in the source code (now removed)
import javax.swing.JTabbedPane;
import javax.swing.plaf.TabbedPaneUI;
public class CreateTabbedPaneUIStressTest {
public static void main(String[] args) {
for (int i=0; i<1000000000; i++) {
JTabbedPane jtp = new JTabbedPane();
TabbedPaneUI tpui = jtp.getUI();
}
}
}
I also monitored the process size using 'top'.
And when I commented out the native call that did the free and re-tested I saw
process size grow.
Turning the above into a useful regression test doesn't seem possible to me.
Limiting Java heap is pointless (and I did use -Xmx20m) since it is a native
resource that is to be freed and failure to dispose won't show up as a problem
without taking down the machine.
