[jira] [Comment Edited] (FELIX-6382) Bundles failing to resolve
because of missing java.* dependencies.
[ https://issues.apache.org/jira/browse/FELIX-6382?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17272436#comment-17272436 ]

-------------------------------------------------------------
[~scott.y], newer versions of bnd do generate imports for java packages. That is correct as this is a feature introduced with OSGi R7 (that bundles can have imports for java.* packages). The framework should export those from the system bundle (and Felix does starting with version 6). Starting with OSGi R8 (available now with Felix 7), you can even have bundles that provide java exports in certain cases (if they are connect bundles).
I would assume your problem is that Karaf isn't exporting the java packages. It likely is overriding the system bundle exports of Felix and doesn't provide the java packages. In that case, you either have to ask Karaf to change that or you have to tell bnd not to generate java imports for your bundles (using {{-nojavaimport=true}}. See [0] for more.

> Key: FELIX-6382
> URL: https://issues.apache.org/jira/browse/FELIX-6382
> Project: Felix
> Issue Type: Bug
> Environment: Windows Server 2016, openjdk-14.0.2+12, Bndtools 5.2.0 Rel
> Reporter: Scott Leschke
> Priority: Major
>
> Not sure how to address this. I previously mentioned this issue on the Karaf user list. I'm trying to upgrade to Karaf 4.3.0 (running under openjdk 14.0) and bundles fail to resolve due to unresolved java.* dependencies.
> I created a bundle with a single class that has a few java.* dependencies and it exhibits the problem as well. I tried compiling the test bundle as 1.8, 9, 11 and 14 and they all behaved the same. The strangest part is that third-party bundles that I rely on, Apache Commons Lang, Google Guava, etc resolve just fine.
> I hesitate to mark this as a Bug since it could be in my environment but I'm at a loss on this at the moment. I'm using the same version of Bndtools that I used with Karaf 4.2.10 and everything works fine there.
