[jira] [Commented] (FELIX-5765) An illegal reflective access operation has occurred

["Rob Walker (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FELIX-5765?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16467059#comment-16467059 ] 

Rob Walker commented on FELIX-5765:
-----------------------------------

FWIW - the following options on our Felix versions gets around these warning temporarily:

   --add-opens java.base/java.lang=ALL-UNNAMED

   --add-opens java.base/java.net=ALL-UNNAMED

   --add-opens java.base/java.security=ALL-UNNAMED

We are on quite an old version though, so it's possible some module/package combinations may be needed in newer Felix versions.

Note that these are very much a workaound rather than a proper fix. Although given the way OSGi actually works, I'm not entirely sure that reflective access and some level of these type of warnings can ever be full avoided.
