[jira] [Comment Edited] (KARAF-6210) NoClassDefFoundError: org/apache/karaf/shell/api/action/Action when starting Karaf
[ https://issues.apache.org/jira/browse/KARAF-6210?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17679216#comment-17679216 ]

-----------------------------------------------------------------
I'm not sure what you mean... I recreated again with a breakpoint in the same place, this time the org.apache.karaf.kar.core bundle hit the exception first. In the debugger if I look at the lower stack frames (the ones around FeaturesServiceImpl) and poke around at the parameters and local variables, it seems like it's processing everything - e.g. a 'requirements' field in a DeploymentRequest object has an entry 'root' and 39 features under it, which I think is everything. In the loop that starts the bundles, the toStart collection has 300 bundles in it, which again, I think is everything that's installed. So I'm not sure if it's a refresh, or just startup... what specifically should I be looking for?
btw in 4.4.3 the exact stacktrace is:

> NoClassDefFoundError: org/apache/karaf/shell/api/action/Action when starting Karaf
> ----------------------------------------------------------------------------------
>
> Key: KARAF-6210
> URL: https://issues.apache.org/jira/browse/KARAF-6210
> Project: Karaf
> Issue Type: Bug
> Components: karaf
> Affects Versions: 4.2.4, 4.3.2
> Environment: Stock Karaf 4.2.4 on Windows 10 with latest Oracle JDK 8.
> Reporter: Amichai Rothman
> Assignee: Jean-Baptiste Onofré
> Priority: Major
> Attachments: karaf_command_not_found.log
>
>
> When starting karaf using equinox and some bundle in the deploy folder, many shell commands (such as bundle:* and others) are not recognized, and the log shows NoClassDefFoundError: org/apache/karaf/shell/api/action/Action. Some commands don't work, but others (e.g. shell:*) do.
> This happens consistently on Windows 10, but not on Linux, not sure why.
>
> Steps to recreate:
> 1. Extract stock Karaf 4.2.4.
> 2. In etc/config.properties change karaf.framework=felix to karaf.framework=equinox.
> 3. Place org.apache.aries.transaction.blueprint-2.2.0.jar (from maven) in deploy folder. This is not the only bundle it happens with, just a public one I found for this example. From several I tried, some recreated the issue and some did not. The bundle is not resolved due to missing dependencies.
> 4. Start Karaf.
> 5. Try to run bundle:list and it'll say command not found. Or look at the karaf log and see "java.lang.NoClassDefFoundError: org/apache/karaf/shell/api/action/Action". Use shell completion to see that some commands are available but others are not.
