I’m currently running OH 2 Build #585 but this behavior started a couple of builds before at least.
Whenever I restart OH now my startup logs are overflowing with:
2016-11-22 11:38:13.479 [INFO ] [g.apache.aries.spifly.dynamic.bundle] - Bundle Considered for SPI providers: org.openhab.core
2016-11-22 11:38:13.481 [INFO ] [g.apache.aries.spifly.dynamic.bundle] - No 'SPI-Provider' Manifest header. Skipping bundle: org.openhab.core
Just about every bundle that makes up OH 2 gets these two lines in the log.
They are informational logs so I assume they are nothing to worry about. To suppress them add the following to userdata/etc/org.ops4j.pax.logging.cf\
# Silence SPI Fly
log4j.logger.org.apache.aries.spifly.dynamic.bundle = WARN, out, osgi:*
