ASM package are not stated as optional imports in the bundle's MANIFEST
-----------------------------------------------------------------------
Key: CXF-1714
URL: https://issues.apache.org/jira/browse/CXF-1714
Project: CXF
Issue Type: Wish
Affects Versions: 2.0.7, 2.1.1
Environment: OW2 JOnAS , using CXF in an OSGi gateway (Felix)
Reporter: Guillaume Sauthier
I've found that the package 'org.objectweb.asm' was in the list of
Import-Package of the bundle.
It's not described as optional, even if in the code (I looked at the
WrapperHelper class) it seems to handle the case where ASM is not present, so I
cannot deploy the CXF bundle if the gateway do not have the 'org.objectweb.asm'
package available.
So it seems logical to add a resolution:=optional statement in the bnd file.
I have described that issue as a wish because there is a simple workaround:
simply provide a bundle exporting the right package; but I don't really like
this solution because, I know, from experience, that ASM is not a easily
shareable library, because of API incompatibilities, it far more easier to
embed its privatized version of ASM (using jarjar or the "new"
maven-shadow-plugin its easy) in a private package: org.apache.cxf.asm. So that
you don't have to describe the imports because ASM is now part of the
distribution + you are sure to never have ASM version incompatibilities issue.
Moreover, the ASM core is really lightweight...
So to sum up, I have 2 solutions:
1. add resolution:=optional to the import statement
2. or privatize ASM automatically
My preference goes to #2 :)
BTW, does that make sens to have a "Bundle" component in JIRA, or the OSGi
issues will go to the "Build system" component ?
