Issue with OSGi Bundle in Installed State After Adding Apache PDFBox to bnd-baseline-maven-plugin

Level 4

I'm facing an issue with my OSGi bundle, which remains in the Installed state after adding Apache PDFBox dependencies to my bnd-baseline-maven-plugin. Here's my setup:

 

 

<dependency>
    <groupId>org.apache.pdfbox</groupId>
    <artifactId>pdfbox</artifactId>
    <version>2.0.9</version>
    <scope>compile</scope>
</dependency>
<dependency>
    <groupId>org.apache.pdfbox</groupId>
    <artifactId>fontbox</artifactId>
    <version>2.0.9</version>
</dependency>
<dependency>
    <groupId>commons-logging</groupId>
    <artifactId>commons-logging</artifactId>
    <version>1.2</version>
</dependency>
<dependency>
    <groupId>org.bouncycastle</groupId>
    <artifactId>bcpkix-jdk15on</artifactId>
    <version>1.61</version>
</dependency>
 

 

bnd Configuration:

 

<bnd><![CDATA[
    Import-Package: javax.annotation,*,!org.bouncycastle.*
    -exportcontents: ${packages;VERSIONED}
    -conditionalpackage: org.apache.pdfbox.*,org.apache.fontbox.*,org.bouncycastle.*
    Bundle-DocURL:
    -plugin org.apache.sling.caconfig.bndplugin.ConfigurationClassScannerPlugin
]]></bnd>

 

Problem:

After installing the bundle, I receive the following error:
sun.java2d.cmm.kcms -- Cannot be resolved and overwritten by Boot Delegation

Additionally, I see the following messages in the bundle:

Hi @georhe6 

 

You could first check you Sling configs, maybe you have something in the bootdelegation property that leads to these errors.

 

Please rewd this documentation, maybe it helps https://sling.apache.org/documentation/configuration.html#osgi-boot-delegation-support-1

Thanks @Tethich , for the feedback.

I did not make any changes at Sling configs level ,after adding these dependencies I am getting the error.

@georhe6 The "Installed" state typically means the bundle could not resolve dependencies. Ensure all the transitive dependencies are resolved and versions are aligned as per the dependency related doc.

- Maybe try updating java to higher versions.

- Try updating pdfbox versions to the latest one.(supporting to current java/JVM)

- Maybe try adding this to the config.properties file:

org.osgi.framework.bootdelegation=sun.java2d.cmm.kcms

- Or you could try Modifying the Bundle's Import-Package Directive to something like- Import-Package: sun.java2d.cmm.kcms;resolution:=optional

Thanks @Manu_Mathew_ ,

We are using java 11 , I have tried with latest versions of pdfbox .
Can you please review the bnd config please.

Both pdfbox and felix are inside org.apache ,I assume some dependency conflict

Hi @georhe6 - Here's a thread from our community https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/can-we-use-pdf-library-wit... on similar issue. Seems like a lower version of the pdfbox works in some cases, and an alternate option of itextpdf has also been discussed.

Hi @georhe6 ,

 

The error sun.java2d.cmm.kcms -- Cannot be resolved and overwritten by Boot Delegation typically happens due to JDK version compatibility or misconfigured OSGi boot delegation.

 

Could you try below-

  1. Add below to your java command or AEM startup script:

--add-exports=java.desktop/sun.java2d.cmm=ALL-UNNAMED

  1. Add the below line to sling.properties:

org.osgi.framework.bootdelegation=sun.java2d.cmm.*,*

 

This will expose the required class and handle boot delegation correctly.

 

Let me know if this works.

 

Thanks,
