This mirrors the lifecycle of a Delayed Component, not a Factory component – see sections 112.5.4 and 112.5.5 of OSGi Compendium spec.</p> <p>This issue tracks two things:</p> <ol> <li>the upstream fix as tracked in <a href="https://issues.apache.org/jira/browse/FELIX-6315" class="external-link" target="_blank" rel="nofollow noopener">https://issues.apache.org/jira/browse/FELIX-6315</a> and its adoption in odlparent</li> <li>a stop-gap mitigation</li> </ol> <p>The mitigation comes in form of <a href="https://issues.apache.org/jira/browse/FELIX-3039" class="external-link" target="_blank" rel="nofollow noopener">https://issues.apache.org/jira/browse/FELIX-3039</a>, i.e. preventing Felix from deactivating unused delayed components.</p> ODLPARENT-242

Although it may be overreaching, adding properly-namespaced attributes to component definitions, so as to localize this to specific components, seems less than convenient.</p> <p>Upstream has accepted the fix, hence it will appear in scr-2.1.24.</p> Development External issue ID <a href="https://issues.apache.org/jira/browse/FELIX-6315">https://issues.apache.org/jira/browse/FELIX-6315</a> Rank 0|i03u6f:
