Thanks. However too late for the spec refresh since it went final on Friday :-( But when the refresh is published, we will list it as an erratum.
Also, you can file bug reports such as these using the OSGi external bugzilla system: http://bundles.osgi.org/bugzilla/ BJ Hargrave Senior Technical Staff Member, IBM OSGi Fellow and CTO of the OSGi Alliance [EMAIL PROTECTED] Office: +1 407 849 9117 Mobile: +1 386 848 3788 Michaël OULLION <[EMAIL PROTECTED]> Sent by: [EMAIL PROTECTED] 07/17/2006 08:51 AM Please respond to [EMAIL PROTECTED]; Please respond to OSGi Developer Mail List <osgi-dev@bundles.osgi.org> To osgi-dev@bundles.osgi.org cc Subject Re: [osgi-dev] osgi-dev Digest, Vol 7, Issue 4 Hi, just an another little error in the OSGi R4 compendium.
