Mail issue on Karaf container

Hi everyone,

I have 2 different servers where I deployed a simple dummy mail application and for some reason on 1 server it doesn't work and It logs:

Caused by: java.lang.LinkageError: loader constraint violation: when resolving method "com.sun.mail.util.PropUtil.getBooleanSessionProperty(Ljavax/mail/Session;Ljava/lang/String;Z)Z" the class loader (instance of org/eclipse/osgi/internal/loader/EquinoxClassLoader) of the current class, javax/mail/internet/MimeMessage, and the class loader (instance of java/net/URLClassLoader) for the method's defining class, com/sun/mail/util/PropUtil, have different Class objects for the type javax/mail/Session used in the signature

The application works properly locally. The configuration, the libraries, the java version are exactly the same on both the server. During the deploy it logs :

2023-01-16 12:26:57,731 | INFO | pool-3-thread-1 | ultOsgiApplicationContextCreator | 243 - org.springframework.osgi.extender - 1.2.1 | Discovered configurations {osgibundle:/META-INF/spring/*.xml} in bundle [DummySendMailAdp (mdw.DummySendMailAdp)]

Thanks for any tips!

Hello @Andrea De Pinto ,

You probably have two different versions of the JavaMail jars in your application and Runtime.

The possible solution:

try to delete the mail folder under <runtime home folder>\system\javax\mail, please zip the folder as a backup first.
restart runtime to re-try?

Hi Achen, thanks for your reply, I really appreciate it. I found the problem, there are files that make conflict with the email lib, so after removing them the process works. These files are :

aws-java-sdk-1.11.397-javadoc.jar

aws-java-sdk-1.11.397-sources.jar

aws-java-sdk-1.11.397.jar

camel-aws-alldep-2.17.3.jar
