             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.
