Description Petr Nejedly 2004-09-14 15:10:43 UTC 
domainsByPackage caches using a String key, which
is generated as a substring from the first-used
class file name. As each of the loaders builds its
own cache and as the file names are constructed on
the fly, duplicate char arrays containing the
names of commonly used classes (like
"java/beans/PropertyChangeSupport.class" are held
many times.
~200kB kan be spared.

Fixed
core/bootstrap/src/org/netbeans/ProxyClassLoader.java,v1.12
Comment 2 Petr Nejedly 2004-09-14 16:11:16 UTC 
Verified using Insane. Really spares nearly 200kB, 150kB on char[],
40kB on String instances.
