-----------------------------------
Summary: Memory leak in Felix Framework Security extension
Key: FELIX-6591
URL: https://issues.apache.org/jira/browse/FELIX-6591
Project: Felix
Issue Type: Bug
Components: Framework Security
Reporter: Chris Rankin
Our project loads and unloads a lot of bundles over time, and we have noticed
that the JVM quickly spends the majority of its time collecting its garbage.
We have identified the Framework Security extension as one source of this
problem. Specifically, the suspiciously large number of `Conditions` and
`Permissions` objects in every heap dump.
The `Permissions` objects are _definitely_ being leaking because
`Permission.Entry.hashCode()` should use `Arrays.hashCode(entry)` instead of
`entry.hashCode()` when `entry` is an array.
I have also reimplemented `Conditions` to listen for `BundleEvent.UNINSTALLED`
instead of relying on multiple `WeakHashMap`s. This is consistent with a TODO
comment for this class, and allows the `Conditions` obejcts to be deleted
_immediately_ instead of waiting for the garbage collector to realise that they
are no longer referenced.
