[jira] [Created] (ARIES-938) Proposal: SPI Catch (plug-in discovery
for both plain Java >=5 and OSGi)
Jeremias Maerki created ARIES-938:
-------------------------------------
Summary: Proposal: SPI Catch (plug-in discovery for both plain Java >=5 and OSGi)
Key: ARIES-938
URL: https://issues.apache.org/jira/browse/ARIES-938
Project: Aries
Issue Type: New Feature
Reporter: Jeremias Maerki
As discussed in http://aries.markmail.org/thread/i2vgjryf5caitqmy I propose a new component for Apache Aries, code-named "SPI Catch", as a complement to SPI Fly.
SPI Catch provides an abstraction to plug-in discovery that for libraries that make use of the JAR service provider mechanism (through META-INF/services) to discover plug-ins. It shields the client from OSGi specifics but all the same offering the dynamics provided through the OSGi service registry. It is an deal counter-part to Apache Aries SPI Fly which is used to publish SPI providers as OSGi services. And finally, another focus is on preserving the runnability totally outside of OSGi.

David Bosschaert commented on ARIES-938:
----------------------------------------
I reviewed the code during the email exchange about this topic, see here: http://markmail.org/message/lpia2uacxe72vku2
and support this submission as I find this an interesting way to 'ease your way into OSGi', by using services that work both inside OSGi and out.
The approach is different from PojoSR (http://code.google.com/p/pojosr)/OSGi Connect (http://www.osgi.org/bugzilla/show_bug.cgi?id=145) in that rather than introducing the OSGi Service Registry APIs early, it actually does not introduce the OSGi APIs at all which some people may find a more attractive way to work.

[jira] [Updated] (ARIES-938) Proposal: SPI Catch (plug-in discovery
for both plain Java >=5 and OSGi)

Jeremias Maerki updated ARIES-938:
----------------------------------
Attachment: spi-catch.zip
The attached spi-catch.zip is the initial proposal. It has a README.txt with some documentation. There is one issue that I haven't been able to fix, yet: The integration tests run from within Eclipse, but there is an exception running it from the Maven build. If anyone has an idea, this would be most welcome. I'm not so familiar with Maven.

Jeremias Maerki commented on ARIES-938:
---------------------------------------
I hereby have to retract the proposal code due to a serious problem with respect to garbage collection which causes services not to be detected in a JVM with aggressive GC options. I will post an updated proposal as soon as I've solved this.
