[jira] Commented: (FELIX-2119) Bundle update fails, if OBR is not installed

["Felix Meschberger (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FELIX-2119?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12840630#action_12840630 ] 

Felix Meschberger commented on FELIX-2119:
------------------------------------------

The problem is caused by the Thread.init method checking whether any security sensitive method, which is not final, is overwritten by the extension of the Thread class. This causes -- in the Sun VM -- all declared methods to be accessed which in turn causes the Resource interface to be required.

By refactoring the BsaeUpdateInstaller class in Rev. 918442/918443 the Thread class is now not overwritten any more and thus the methods are not accessed any longer. This should fix this issue.

> The reason for this is that UpdateHelper depends on OBR service API. While OBR is not a core service, its absence shouldn't disallow execution of normal bundle life-cycle commands.
