[jira] [Commented] (COMPRESS-552) OSGI check broken - try to load class BundleEvent always fails

    [ https://issues.apache.org/jira/browse/COMPRESS-552?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17296638#comment-17296638 ] 

Stefan Bodewig commented on COMPRESS-552:
-----------------------------------------

I'm afraid the accepted answer of the StackOverflow question would suffer from the same problem ({{FrameworkUtil}} probably isn't available either). So the only way out would be a Bundle-Activator?

>             Project: Commons Compress
>          Issue Type: Bug
>          Components: Compressors
>    Affects Versions: 1.20

> There is a check for running in OSGI env. in {{ZstdUtils}}, {{BrotliUtils}}, {{LZMAUtils}} and {{XZUtils}} like this:
> {code:java}
> static {
>     cachedZstdAvailability = CachedAvailability.DONT_CACHE;
>     try {
>         Class.forName("org.osgi.framework.BundleEvent");
>     } catch (final Exception ex) { // NOSONAR
>         setCacheZstdAvailablity(true);
>     }
> }
> {code}
> Loading the class {{org.osgi.framework.BundleEvent}} always fails because {{Import-Package}} directive for {{org.osgi.framework}} is missing in _MANIFEST.MF_. Or it requires another more sophisticated approach (https://stackoverflow.com/q/5879040/1061929).
> Tested with Eclipse 4.14 (org.eclipse.osgi_3.15.100.v20191114-1701.jar)
