------------------------------------------
Summary: Reduce memory allocation in
org.apache.aries.blueprint.proxy.Collaborator class
Key: ARIES-1319
URL: https://issues.apache.org/jira/browse/ARIES-1319
Project: Aries
Issue Type: Improvement
Components: Blueprint
Affects Versions: blueprint-core-1.4.2
Reporter: Dmitry Konstantinov
In case of intensive usage there is an memory and CPU overhead in
org.apache.aries.blueprint.proxy.Collaborator which can be easy eliminated:
1) Stack has a thread safety overhead, it can be replaced by ArrayDeque, the
stack is used in a single thread
2) In case of there are no interceptors - it make sense to not allocate each
time a Stack object. The reference can be set to null or a static immutable
empty stack value.
