Hi all,
just want to share this: I've switched to Java 7 (Oracle JDK 7 on Linux)
this week for another project and when I tried to start Matterhorn it
gave me a lot of framework errors about unresolved package dependencies
and also a few NoClassDefFoundErrors.
It appears that under Java 7 certain packages are by default not visible
for classes inside Felix, though they were under JDK6. This is a known
effect [1]. As a workaround I added [2] the to my
FELIX_HOME/conf/system.properties. Seems to work. When a package is
added to the org.osgi.framework.system.packages.extra property it
becomes visible inside the container.
...as this will most likely be the case for every new package of the
flavor javax.*, org.w3c.* and such, be warned if you switch to Java 7 now ;)
Cheers,
Benjamin
