<Swing Dev> [8] Review request for 8028054: com.sun.beans.finder.MethodFinder has unsynchronized access to a static Map

[sergey malenkov]

Hello,

Could you please review the following fix:
fix: http://cr.openjdk.java.net/~malenkov/8028054.8.0/
bug: https://bugs.openjdk.java.net/browse/JDK-8028054

There is an unsynchronized access to internal caches.
I've synchronized both caches (for methods and constructors) .

The 8023310 issue shows how is slow a simple synchronization.
So I've created the Cache class that is similar to WeakIdentityMap.
Later we could remove WeakIdentityMap which is a special case of Cache.

Thanks,
SAM
