possible roiManager bug

[Aryeh Weiss]

The following command:

roiManager("Set Color", colorRoi);

successfully changes the selected ROi color. However, it throws the
following exception:


java.lang.NullPointerException
        at ij.plugin.frame.RoiManager.setProperties(RoiManager.java:1077)
        at ij.plugin.frame.RoiManager.runCommand(RoiManager.java:1635)

        at ij.macro.MacroRunner.run(MacroRunner.java:143)

Do I have a mistake in the command, or is this a bug?

This bug is fixed in the ImageJ 1.45p daily build.
