Re: [jetty-dev] Eclipse BIRT and Jetty 9.4.3
hi all,

it looks like the problem lies with the BIRT Jar files:

Maybe they have been signed with an hashing algo that is no longer considered secure and has been disabled in Java 8 _121.

In any case the original stack trace did not show the reason of the failed class loading hence I was misled into thinking that Jetty was somehow responsible.

I obtained these stacktraces by switching to my build setup which uses an actual web app / WEB-INF/lib etc whilst before I was actually using a Test-only embedded Jetty set up on which the class loaded behaved differently.

Thanks a lot for your help and sorry for not doing my homework before bothering the list.. I just saw that you guys were talking about it and jumped right in :)


thanks,
Michele

hi Jan,

I have just tried again with BIRT v 4.6.0-20160607 and Jetty 9.4.3:

<dependency>
<groupId>org.eclipse.birt.runtime</groupId>
<artifactId>org.eclipse.birt.runtime</artifactId>
<version>4.6.0-20160607</version>
</dependency>

Looking at the Maven dependencies tree I could not find any reference to the  jetty-osgi-boot-9.2.13 jar that you mention below.

I tried to declare it as a dependency anyway but it did not work:

<dependency>
<artifactId>jetty-osgi-boot</artifactId>
<groupId>org.eclipse.jetty.osgi</groupId>
<version>${jetty.version}</version>
<scope>runtime</scope>
</dependency>



This is the stacktrace I get:

If I try to declare all BIRT transitive dependencies manually I get a similar error with the only difference being the name of the BIRT class that can not be loaded:

Caused by: java.lang.ClassNotFoundException: org.eclipse.birt.core.framework.PlatformConfig

I can see that this is caused by some weird classloading problem but unfortunately I don't have a clue on how to fix this nor I can invest an inordinate amount of time on this :(


Thanks for looking into it, very much appreciated.

Michele

Joakim,

The Birt project has a hard dependency on jetty-9.2.13. Moreover, their p2 repository contains the jetty-osgi-boot-9.2.13 jar. If a user already has another version of the jetty-osgi-boot jar installed, Eclipse reports the conflict.

I don't see that there is anything we can do about it. Birt would need to upgrade to jetty-9.4, or at least be less restrictive in the versions of jetty-osgi-boot jar that they interwork with.

cheers

Looks like the BIRT project is having conflicts with the Jetty 9.4.3 bundles.


Anything we should do to fix it?
Or are the 9.4.4 fixes for OSGi (soon to be released) going to help?
