[jira] [Updated] (ARIES-1051) Blueprint dealock is occured during
Karaf startup or bundle update action
[ https://issues.apache.org/jira/browse/ARIES-1051?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dmitry Konstantinov updated ARIES-1051:
---------------------------------------
Description:
There are two locks - felix bundle lock and lock of {code}AtomicBoolean scheduled{code} in BlueprintContainerImpl class and these locks can be occured in diferent order for some situations.
For example:
1) In case of container initialization the order is following: blueprint lock (inside executor task) -> bundle lock (inside service registration)
2) In case of container destroying: bundle lock (bundle tracker) -> blueprint lock (BlueprintContainerImpl.namespaceHandlerUnregistered method)
The thread dump provides a real example of the deadlock:
