Richard S. Hall commented on FELIX-3887: ---------------------------------------- I remember someone else mentioning this bug a little while back and I even remember looking into it, but I cannot find a bug report, nor can I see a commit message that says it addresses this. However, it does appear to work on trunk: g! lb START LEVEL 1 ID|State |Level|Name 0|Active | 0|System Bundle (4.1.0.SNAPSHOT) 1|Active | 1|Apache Felix Bundle Repository (1.6.6) 2|Active | 1|Apache Felix Gogo Command (0.12.0) 3|Active | 1|Apache Felix Gogo Runtime (0.10.0) 4|Active | 1|Apache Felix Gogo Shell (0.10.0) 5|Installed | 1|require.system.bundle.test (0.0.0) g! headers 5 Bundle 5 -------- Bundle-ManifestVersion = 2 Bundle-SymbolicName = require.system.bundle.test Created-By = 1.6.0_37 (Apple Inc.) Manifest-Version = 1.0 Require-Bundle = system.bundle g! start 5 DEBUG: WIRE: [5.0] osgi.wiring.bundle; (osgi.wiring.bundle=system.bundle) -> [0] g! So maybe it is fixed.
