> for (int i=0;i<1000*1000;i++) {
> ThreadLocal t = new ThreadLocal();
> t.set(new Object());
> t.set(null);
> }

> After short investigation of JET/GC problem I found that JET gc report looks valid: java/lang/FinalizerThread is being reported.
> GC fails because it founds broken references from this root-object to another ones.
