Description:
1. start IDE with jdk 1.5
2. create project with JPanel and JFrame.
3. Insert some swing in JPanel and compile project
4. Set jdk 1.6 platform in IDE
5. Change project from 1.5 to 1.6 jdk and compile the project
6. Through palette manager (add from project), add JPanel into Pallete
7. open JFrame from this project and try to insert JPanel from Pallete into it
Then a message occures but it's not clear and user doesn't know what's the
problem and what is the reason of no possibility to add this java bean in JFrame.

Now IDE announce:
"Annotation: Cannot load component class nn.testicek from project:
E:\testing_NB\integration\JavaApplication3.
The class must be compiled and must be on the classpath of the project this form
belongs to."
