[jira] [Updated] (KARAF-4169) Blueprint creates unnecessary
prototype bean instances
[ https://issues.apache.org/jira/browse/KARAF-4169?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Viktor Kozlov updated KARAF-4169:
---------------------------------
Description:
After creating all necessary prototype instances, blueprint create one more instance for each prototype bean. It can be a huge trouble when there is deep prototype bean tree.
Here is simple example to demonstrate it: http://www.lorien.biz/karaf/test.zip
-- normal creation --
Server1 create bpt.test.internal.Server1@67ea2a02
Server2 create bpt.test.internal.Server2@72af85f3
Consumer1 create bpt.test.internal.Consumer1@35fc15f7
injected_s1 bpt.test.internal.Server1@67ea2a02
injected_s2 bpt.test.internal.Server2@72af85f3
MyServlet create bpt.test.internal.MyServlet@612307e7
injected_c bpt.test.internal.Consumer1@35fc15f7
-- normal creation ends --
-- unnecessary creation of Server 1 --
Server1 create bpt.test.internal.Server1@6f878ffd
-- unnecessary creation of Server 1 ends --
-- unnecessary creation of Server 2 --
Server2 create bpt.test.internal.Server2@2cfe643f
-- unnecessary creation of Server 2 ends --
-- unnecessary creation of Consumer (with its all dependencies which are prototypes too) --
Server1 create bpt.test.internal.Server1@71677b2c
Server2 create bpt.test.internal.Server2@40c7bfde
Consumer1 create bpt.test.internal.Consumer1@7a05a90b
injected_s1 bpt.test.internal.Server1@71677b2c
injected_s2 bpt.test.internal.Server2@40c7bfde
-- unnecessary creation of Consumer ends --
