Kestrel-F regression: java.awt.im.InputContext.selectInputMethod

Name: mgC56079 Date: 06/04/99


According to the spec this method should never throw an exception:
    /**
     * Selects an input method that supports the given locale.
     * If the currently selected input method supports the desired locale
     * or if there's no input method available that supports the desired
     * locale, the current input method remains active. Otherwise, an input
     * method is selected that supports text input for the desired locale.
     * Before switching to a different input method, any currently uncommitted
     * text is committed.
     * If the platform does not support input methods or the desired locale,
     * then false is returned.
     *
     * <p>
     * A text editing component may call this method, for example, when
     * the user changes the insertion point, so that the user can
     * immediately continue typing in the language of the surrounding text.
     *
     * @param locale The desired new locale.
     * @return Whether the input method that's active after this call
     * supports the desired locale.
     */
    public boolean selectInputMethod(Locale locale) {

This no longer works in JDK-Kestrel (build F):
----- Minimized test: IM1.java -----
import java.awt.im.*;
import java.util.Locale;

public class IM1 {
    public static void main(String args[]) {
        InputContext anInputContext = InputContext.getInstance();

        if ( anInputContext == null ) {
            System.out.println("skipping the test");
            return;
        }

      anInputContext.selectInputMethod(Locale.JAPANESE);
      System.out.println("passed");

    }
}
----- Output (JDK1.2, correct) -----
% java IM1
passed
----- Output (JDK-Kestrel, wrong) -----
% java IM1
