Description Jaromir Uhrik 2001-11-09 17:11:20 UTC 
[dev build #200111090100; jdk1.4]
When I start the UC wizard and connect to the UC server then in the ide.log 
appears the code below (I used the switch -J-Dnetbeans.debug.exceptions=true to 
have the warning in more readable form).

Fri Nov 09 16:54:19 CET 2001: java.lang.Throwable: Warning: multiple instances o
f shared class org.netbeans.modules.autoupdate.UpdateNode$1 created.
Nested annotation: First instance created here
java.lang.IllegalStateException: Warning: multiple instances of shared class org
.netbeans.modules.autoupdate.UpdateNode$1 created.
