Document

Tries to perform a "full" garbage collection cycle (including processing of weak references and invocation of finalize methods) and waits for it to complete.

Usage

From source file:com.google.inject.internal.WeakKeySetUtils.java

public static void awaitFullGc() {
    // GcFinalization *should* do it, but doesn't work well in practice...
    // so we put a second latch and wait for a ReferenceQueue to tell us.
    ReferenceQueue<Object> queue = new ReferenceQueue<Object>();
    WeakReference ref = new WeakReference<Object>(new Object(), queue);
    GcFinalization.awaitFullGc();
    try {//from w w w.ja va 2  s  .  c o  m
        assertSame("queue didn't return ref in time", ref, queue.remove(5000));
    } catch (IllegalArgumentException e) {
        throw new RuntimeException(e);
    } catch (InterruptedException e) {
        throw new RuntimeException(e);
    }
}
