java.lang.ClassNotFoundException: javax.crypto.spec.SecretKeySpec

[unnikrishnan kv]

Hello Team, Am working in AEM project. I need to add jose4j for livefyre dependencies.So i converted jose4j 4.3 to OSGI bundle and uploaded in AEM. It is working fine in compile time and run time throws exception like "Caused by: java.lang.ClassNotFoundException: javax.crypto.spec.SecretKeySpec". Could you please help to fix this.

I don't really know, to be honest.

I will say that pull request #5 was to "Make OSGi bundle from resulting JAR" and that's been part of the project since v0.4.4. You might want to try with a newer version than 0.4.3. I'll note that the MANIFEST.MF from 0.5.2 has "Import-Package:...", which the attached jar manifest does not. And one of the packages is 'javax.crypto.spec' which is the package of SecretKeySpec that the exception is complaining about.
