Daniel Sun updated GROOVY-9631:
-------------------------------
Description:
*BACKGROUND*
Groovy home-made data structures are lack of maintainence for a long time, so
it's better to replace them with mature and continuous improving data structure
from JDK
*DONE*
Some internal legacy data structure are replaced with Java collection:
# Deprecate redundant {{AbstractConcurrentMapBase}},
{{AbstractConcurrentMap}}, {{ManagedConcurrentMap}}, and their related inner
classes, e.g. {{Entry}}
# Replace {{ManagedConcurrentMap}} with {{ManagedIdentityConcurrentMap}},
which is base on {{ConcurrentHashMap}}
See [https://github.com/apache/groovy/pull/1306]
*TODO*
# Deprecate {{ComplexKeyHashMap}}, {{SingleKeyHashMap}} and
{{TripleKeyHashMap}}. Note: {{TripleKeyHashMap}} is only used by never called
method
# Polish {{Index}} and {{MethodIndex}} in the class {{MetaClassImpl}}, they
derive from {{TripleKeyHashMap}}
# Polish {{MetaMethodIndex}}, which is actually trying to implement hash map
but it could rely on Java collection too
