Hi Steve.
I added the following three lines to the code suggested in your reply:
Class dummy =
this.getClass().getClassLoader().loadClass("de.jb.compo.MyComponent");
loggerInst.debug(dummy.getName());
loggerInst.debug("isInterface(): " + dummy.isInterface());
The output:
#1st time
here : 23361497
there: 2730814
de.jb.compo.MyComponent
isInterface(): true
(...)
#2nd time
here : 23361497
there: 2730814
de.jb.compo.MyComponent
isInterface(): true
(...)
