Exception when starting gogo
Hello,
I am using Gogo 0.8.0 and I run it with Equinox. I noticed that when Gogo starts, an exception is printed before the Gogo prompt becomes available. The exception is caused by the execution of the default gosh_profile script in org.apache.felix.gogo.shell bundle. Particularly the fragment ${.context} bundle 0 in addcommand system ((${.context} bundle 0) loadclass java.lang.System) is not evaluated correctly. The evaluation tries to call BundleContext.getBundle(String location) with argument 0, instead of BundleContext.getBundle(long id). The evaluation returns null, because there is no bundle with such location and the whole evaluation fails with the exception bundleresource://3.fwk25675100/gosh_profile: ERROR: java.lang.RuntimeException: Command name evaluates to null: ${.context} bundle 0.
Any workaround for this? However, it is not a big problem, since the shell is fully operational after that.
Regards,
Lazar

"System Bundle" is the standard location of the system bundle...it is in
o.o.f.Constants.

Not unless "System Bundle" happens to be the location of the bundle:
public Bundle getBundle( String location )
Parameter location - The location of the bundle to retrieve.
Returns - the bundle with the specified location.
A Bundle object or null if the location does not match any installed bundle.
Since: 1.6

I suppose you could also do:
bundle "System Bundle"
Right?

Thanks Derek. Then I will probably replace the default gosh_profile.

I tripped across this yesterday.
I've explained the problem in this jira:
https://issues.apache.org/jira/browse/FELIX-2927
The work-around is to replace
bundle 0
with
(bundles) 0
the former attempts to invoke getBundle(long) but actually invokes
getBundle(String)
the latter invokes getBundles() and then returns the first element.
