Re: [equinox-dev] Multiple bsnversion in equinox

I'm not sure I understand why you're surprised?

If you install a bundle with the same location and the already installed 
bundle is visible to the context, the install will succeed and you will 
receive a reference to the already installed bundle. If the already 
installed bundle is not visible to the context, the install will fail and 
you will receive a BundleException indicating the operation was rejected 
by a hook. This will happen regardless of the value of the bsnversion 
property because locations must be unique.

If you install a bundle with the same bsn and version as an existing 
bundle, and the location is unique, and the bsnversion property is set to 
'single', the install will fail and you will receive a BundleException 
indicating the bundle is a duplicate. If the bsnversion property is set to 
'multiple', the install will succeed and you will receive a new Bundle 
object with a unique ID. Whether or not the bit source is the same should 
not make any difference as far as I know.

[equinox-dev] Multiple bsnversion in equinox






Hi, 
 
I start Equinox with org.osgi.framework.bsnversion=multiple and try to 
install one bundle twice:
 
osgi> install reference:
file:C:\eclipses\eclipse-SDK-3.7RC4-win32-x86_64\eclipse\plugins\com.ibm.icu.source_4.4.2.v20110208.jar
Bundle id is 5
 
osgi> install initial@reference:
file:C:\eclipses\eclipse-SDK-3.7RC4-win32-x86_64\eclipse\plugins\com.ibm.icu.source_4.4.2.v20110208.jar
Bundle id is 6
 
The installation is successful even if locations strings are not equal but 
resolve to the same file.
Is that expected? 
 
Thanks, 
Katya_______________________________________________
