The format of a descriptor
is defined in JVMS 4.3.2. Typical
descriptors are:
I
(Integer)
Lpkg1/pkg2/Cls;
(Class declared in package)
Lpkg1/pkg2/Outer$Inner;

Notice that this method is never called from more than one thread at a time. In other words, implementations of this method need not be synchronized.

If an IClass
with that descriptor already exists, a
