I agree. But, could the hashtable be collected before since it has not references in the method? Or is
TemplatesCache.getInstance().get("key");
considered as a reference?
Thanks

As long as the objects aren't wrapped in weak references, I don't see how
they would get garbage collected (they still have an active reference in the
hashtable)

Sorry, of course I meant the unique instance of the static class.
We have a templates caches filled under demand, and implemented as a
singleton hashtable. We suspect that GC could be cleaning the cache.
Under heavy stress we are getting some errors and we are looking for the
source.
The invocations are in some methods:
TemplatesCache.getInstance().put("key", object);
or
TemplatesCache.getInstance().get("key");
They have not any more references that the previous ones from the rest of
the code. Are they enough to avoid being GC'd?
Adolfo.
