Description

Name: skT45625			Date: 05/16/2000


java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-C)
Java HotSpot(TM) Client VM (build 1.3.0-C, mixed mode)

After switching from jdk1.2.2 using auxiliary LAFs fails. The program hits an
uncaught exception in Hashtable.get(Object key) which is called by
UIDefaults.get(Object key). This error is caused by a missing entry for
  RootPaneUI in the UIDefaults table.

FIX: JRootPane.getUIClassID() should either return "MultiPaneUI" or the key
should be added to MultiLookAndFeel's UIDefault table.

WORK AROUND Name: skT45625 Date: 05/16/2000 Specify swing.plaf.multiplexinglaf=myProperMultiLAF in swing.properties, override getDefaults() from MultiLookAndFeel and add a key value pair for RootPaneUI, "javax.swing.plaf.multi.MultiPaneUI". ======================================================================

EVALUATION MultiLookAndFeel lacks an UI class for JRootPane. ###@###.### 2000-05-22 MultiRootPaneUI has been created. scott.violet@eng 2000-06-30

SUGGESTED FIX Create a new class: javax.swing.plaf.multi.MultiRootPaneUI and add it to Multi LAF defauls table. Alternatively, we can probably use MultiPanelUI for JRootPane, since there is no big differences between Multi UI classes. The diffs that follow are for the first approach. I used a test (from Graphic Java book) to verify this fix. This test (3 files) is attached. /* * %W% %E% * * Copyright 1997-2000 Sun Microsystems, Inc.
