7 years ago Before, with java 7 I get lock in the WeakHashMap#get, like in the article http://www.adam-bien.com/roller/abien/entry/endless_loops_in_unsychronized_weakhashmap
But with java 8, lock happens in the transfer method:
/** Transfers all entries from src to dest tables */
private void transfer(Entry<K,V>[] src, Entry<K,V>[] dest) {
for (int j = 0; j < src.length; ++j) {
Entry<K,V> e = src[j];
src[j] = null;
while (e != null) {
Entry<K,V> next = e.next;
Object key = e.get();
if (key == null) {
e.next = null; // Help GC
e.value = null; // " "
size--;
} else {
int i = indexFor(e.hash, dest.length);
e.next = dest[i];
dest[i] = e;
}
e = next;
}
}
}

Sometimes (30-40%) in dev just after app startup all application become frozen during loading js-css. Every time in dead lock happens WeakHashMap
