Typesafe console and OSGI issues

[Stavros Kontopoulos]

I am trying to create a multiple bundle osgi akka based project and integrate it with typesafe console.


So far i can make it work with one bundle (all dependencies in one jar file (transitive ones) ) but it does not work as expected when i use more than one bundles.

To make things easier i used only two independent bundles each of which has each own set of dependencies resolved within its own jar without importing anything from one  another.

This level of isolation was on purpose to find possible issues, before going too far.

I deployed the bundles and i got this exception error:

It seems a classloader issue but i dont understand why...


I use:

Karaf 2.2.3:

under karaf system:

org.eclipse.equinox.weaving.aspectj_1.0.300.v20130327-1442.jar
org.eclipse.equinox.weaving.caching_1.0.300.v20130327-1442.jar
sigar folder with dlls packaged within the typesafe console zip file

under karaf lib:

org.eclipse.equinox.weaving.hook_1.0.200.v20130327-1442

in karaf.bat:
set DEFAULT_JAVA_OPTS=%JAVA_MODE% -Xms%JAVA_MIN_MEM% -Xmx%JAVA_MAX_MEM% -Dderby.system.home="%KARAF_DATA%\derby" -Dderby.storage.fileSyncTransactionLog=true -Dcom.sun.management.jmxremote -Dorg.aspectj.tracing.factory=default -Djava.library.path=sigar/

etc/config.properties:

karaf.framework=equinox


Contents of each bundle are as follows


META-INF
sample
akka-osgi_2.10-2.2.1.jar
akka-slf4j_2.10-2.2.1.jar
application.conf
atmos-event_2.10-1.3.1.jar

trace-akka-2.2.1_2.10-1.3.1.jar
trace-scala-2.10.2-1.3.1.jar
uncommons-maths-1.2.2a.jar

and

i have for aop.xml (instead of unjar aop.xmls i gethered them together -not perfect but ok ;)):

<aspectj>
    <aspects>

        <!--<aspect name="com.typesafe.atmos.trace.RemoteTraceAspect"/>-->
        <aspect name="com.typesafe.atmos.trace.ActorTraceAspect"/>
        <aspect name="com.typesafe.atmos.trace.FutureTraceAspect"/>
    </aspects>
    <weaver options="-verbose">
        <include within="akka..*"/>
        <!-- Weaving with ByteString included throws a VerifyError -->
        <exclude within="akka.util.ByteString"/>
        <include within="com.typesafe.atmos..*"/>
        <include within="scala.concurrent..*"/>
    </weaver>
</aspectj>

Custom aspects defined by me work fine....

I am thinking of using one bundle as a common bundle to share libraries such as trace-akka-2.2.1... has anyone had success with osgi before?

Any ideas?
