Java 16 error in "HTreeMap.put()": Unable to make field final java.util.Collection java.util.Collections$UnmodifiableCollection.c accessible #990

Open ksilz opened 3 years ago

ksilz commented 3 years ago

Hi,

I switched to Java 16 today, and the put() below produces an error. It works with Java 15. My code is compiled with Java 14.

HTreeMap<String, V> cache = this.openCache(expirationTime, expirationTimeUnit);
cache.put(key, value);

Here's the stacktrace:
