Subject Karaf 4.2.5 + Equinox + SCR: error
Date Thu, 16 May 2019 20:11:30 GMT
Hi,

is it already known that using Equinox on Karaf 4.2.5 will result into
an exception if the "scr" feature is installed?

* Unpack official distribution (tar xzf apache-karaf-4.2.5.tar.gz)
* Edit "etc/custom.properties" and add the line "karaf.framework = equinox"
* start Karaf
* install SCR feature (feature:install scr)
* identify an error
