Avoid creating WeakEntry wrappers when looking up cached MethodType

    Details

    • Type: Enhancement
    • Status: Resolved
    • Priority: P4
    • Resolution: Fixed
    • Affects Version/s: 12
    • Fix Version/s: 12
    • Component/s: core-libs

      Description

      The interning mechanism for MethodType could be improved to not need to instantiate a WeakEntry when doing lookups. This gives a small but measurable improvement on startup tests setting up lambdas (~0.5-1%) and indified string concat (~2-4%).
