Are legal concerns of using Netty's ConcurrentWeakKeyHashMap the only issue with Melloware's PR (https://github.com/apache/commons-beanutils/pull/56) from a couple of years ago? That PR mentions http://creativecommons.org/licenses/publicdomain for details on the license, which unfortunately no longer works. However, looking at the Netty source (https://github.com/netty/netty/blob/3.9/src/main/java/org/jboss/netty/util/internal/ConcurrentWeakKeyHashMap.java), they have an Apache 2 license. Doesn't that alleviate any license concerns? Can we resuscitate Melloware's PR and wrap up this issue? Thanks, Josh.
