> Key: KARAF-7271
> URL: https://issues.apache.org/jira/browse/KARAF-7271
> Project: Karaf
> Issue Type: Bug
> Components: karaf
> Affects Versions: 4.2.11, 4.2.12
> Reporter: Miel Donkers
> Assignee: Jean-Baptiste Onofré
> Priority: Major
>
> Karaf 4.2.11 upgraded org.ops4j.pax.url from version 2.6.3 to 2.6.7
> ([https://github.com/apache/karaf/pull/1290/files)]
> With that pax.url version, the bnd lib were updated from 2.3.0 to 5.2.0 (see
> [https://github.com/ops4j/org.ops4j.pax.url/blob/11f5e7db4d6eace783c448349395f314b5498998/pom.xml#L68]
> and
> [https://github.com/ops4j/org.ops4j.pax.url/blob/7b59243313bb3cb3ddac3908680663a612e994f5/pom.xml#L68]
> )
> With this update of bnd lib, a issue was introduced (since bnd lib 4.0.0)
> where even loading relatively small JAR files can lead to major memory
> overhead (JAR file of 11 Mb needs 350+ Mb to get loaded). In
> memory-constrained environments, for example running a Karaf application on
> Kubernetes with memory limits applied, this will lead to issues where the app
> goes out of memory or gets killed.
> The problem was flagged with bnd lib here:
> [https://github.com/bndtools/bnd/issues/4901]
> And they already provided a fix:
> [https://github.com/bndtools/bnd/commit/89743f9ed2554981934b71df301572665ef95dcd]
> However at the moment of writing there is no new version of bnd yet including
> the fix (and thus neither is there for org.ops4j.pax.url).
> Requesting to update those dependencies whenever a fix is available and
> released.
