I use the method Injector.createChildInjector(...) to create many injectors 
with different configurations in my application.
Each of those injectors is only used for a short period of time and then 
garbage collected.

Now it seems that for each injector an own set of fast classes is created 
for each SingleMethodInjector and others.
For an example look at:
https://github.com/google/guice/blob/f905d59ac9c3c1ad57c755a1abb29c4fb2d6b7fa/core/src/com/google/inject/internal/SingleMethodInjector.java#L46

These fast classes (or at least meta data about them) are kept within a 
global map.
The Eclipse Memory Analyzer classifies this as a leak suspect:

One instance of "java.util.HashSet" loaded by "<system class loader>" 
occupies 671,209,552 (79.21%) bytes. 
The instance is referenced by 
com.google.inject.internal.cglib.core.$AbstractClassGenerator$1 
@ 0xfff4c7a0 ,
loaded by "com.google.inject". The memory is accumulated in one instance of 
"java.util.HashMap$Node[]" loaded by "<system class loader>".


I think it should be possible for Guice to share the fast classes between 
different injectors.

Any help is appreciated.

Thank you and best regards,
Ken
