My system is using equinox config.ini to configure bundles and my question
is when the system got re-started the previous started bundle via URL has
native code (Bundle-NativeCode: in the manifest.mf) and the native code has
been updated so my question is what the equinox will do with the updated
native code? I notice the native code has been copied into the
org.eclipse.osgi/bundles directory and restart with the new bundle did not
cause the new native code being copied into the org.eclipse.osgi/bundles
directory again.

What protocol is used for you install URLs? Are you using plain "file:"
URLs or "reference:file:" URLs? If you are using plain "file:" URLs
then the content of the bundle is copied into the framework cache and
the framework never reads the original location of the content again.
If you are using "reference:file:" URLs then the framework will use the
content of the bundle as-is from the file location. But we assume the
content will not change out from underneath us. You must use OSGi apis
to install/update the new content.

How did you update the native code? Is the native code in a jar'ed
bundle or a directory bundle? If the bundle is jared and you simply
replaced the jar file on the file system then we will not recognize that
a new library is available in the jar and will not extract the new content.

The framework assumes that bundles will be updated using OSGi APIs so
that the framework can be informed about the updated bundle.

We are using "reference:file:" URLs.

The native code is in a jar bundle and how can I make Equinox to perform
native code update when it is in a jar file?
