Hi,

a small improvement can be seen on startup tests that exercise lambdas and ISC if we change the interning mechanism of MethodTypes slightly so that lookup can be done without wrapping the lookup key in a WeakEntry.

Bug: https://bugs.openjdk.java.net/browse/JDK-8209633 Webrev: http://cr.openjdk.java.net/~redestad/8209633/open.00/

Testing: jdk-tier1+jdk-tier2

Thanks!

/Claes
