*Flags and ClassLoaders*

Flags and ClassLoaders API has changed.  In the past, the following would work:

{code}
cache.withFlags(f1, f2);
cache.withClassLoader(cl);
cache.put(k, v);
{code}

In 5.1.0, these withX() methods return a new instance and not the cache itself, so thread locals are avoided and the code above will not work.  If used in a fluent manner however, things still work:

{code}
cache.withFlags(f1, f2).withClassLoader(cl).put(k, v);
{code}

The above pattern has always been the intention of this API anyway.
