> BasicCapability should take advantage of the effective immutability of
> capabilities.

> Key: ARIES-1390
> URL: https://issues.apache.org/jira/browse/ARIES-1390
> Project: Aries
> Issue Type: Improvement
> Components: Subsystem
> Affects Versions: subsystem-2.0.2
> Reporter: John Ross
> Assignee: John Ross
> Priority: Minor
> Labels: perfomance
> Attachments: BasicCapability-Screenshot-Java Monitor.png,
> BasicCapability-after.cpu, BasicCapability-before.cpu,
> ManyFeaturesWithSharedBundlesTest.java

>
> Currently, when given an already existing Capability at construction,
> BasicCapability will make a copy of the attributes and directives. This is
> not really necessary since a properly implemented Capability will be
> effectively immutable as required by the OSGi API.
> Profiling showed that BasicCapability(Capability, Resource) was taking up
> 4.6%, or 1550 ms, of the total time. After the optimization, this no longer
> registered with a sampling time of 50 ms.
> BasicCapability(Capability, Resource) will now simply reuse the already
> existing, and effectively immutable, attribute and directive maps of the
> provided capability.
