Bug 49353 Javadoc preference does not indicate bad exe until field is edited. [javadoc]
I upgarded from Sun Java 1.4.2_02 to 1.4.2_03. When I open the Javadoc preference page, the entry fields shows "C:\Java\sun\1.4.2_02\bin\javadoc.exe", which no longer exists but the error icon and message is NOT displayed at the top of the pane. If I edit the field but leave the entry still bogus, THEN the error icon and message appear. I think the error should appear as soon as the pane is displayed. Version 3.0.m6.
