             Summary: Style engine : style matching allocates a lot of memory even if everything is in cache
                 Key: FLEX-33890
                 URL: https://issues.apache.org/jira/browse/FLEX-33890
             Project: Apache Flex
          Issue Type: Improvement
          Components: Mobile: Performance, Performance: Framework, Styles
    Affects Versions: Apache Flex 4.11.0
         Environment: mobile desktop
            Reporter: Benoit Wiart


StyleProtoChain#getTypeHierarchy is called often and is responsible for a lot of unneeded memory allocations even if the type hierarchy is cached.

This patch has 2 parts :
- (1) : exception handling reworking in order to avoid the closure/activation creation by the try/catch
- (2) : replace the use of a flash proxy with a custom class : It seems that the proxy was only used as an array.
