Any ideas what this refers to?

Subject: Weak References

If we are seeing a huge build up of weak references:

sun/rmi/transport/WeakRef =>
      1654973  1644293  10680       0      0 Total
       794333   783888  10445       0      0 => com/sas/metadata/remote/MdObjectListImpl
       194966   194966      0       0      0 => com/sas/metadata/remote/impl/PropertyImpl
      192165   192165      0       0      0 => com/sas/services/information/metadata/OMRProperty

When does the GC algorithm decide to collect? Is there something that can be done programatically to collect earlier?

I assume GC will not collect until the weak references are "dead", i.e. the referents are available for GC since no strong refs are pointing at the referent?

Any guidance appreciated.
