java.lang.NullPointerException:
[ https://issues.apache.org/jira/browse/CAMEL-15156?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jan Bednar resolved CAMEL-15156.
--------------------------------
Resolution: Not A Bug
maven-assembly-plugin does not work well with Apache Camel because it overrides type converter manifests. Use maven-shade-plugin. [https://camel.apache.org/manual/latest/faq/how-to-create-executable-jar-camel-main.html] .

> There is an issue with smtp endpoint, it fails with a null pointer exception when the project is run as a standalone jar file.
> NOTE: This is not an issue when I use the mvn compile exec:java.
> Steps to replicate:
> # create a simple maven project with apache-camel arch (Here is bare bone code sample [https://github.com/drkaleem/test_camel_mail])
> # Use any fake smtp server running on port 25. Or run "sudo python -m smtpd -n -c DebuggingServer localhost:25" to fire up one on your local machine.
> # THE GOOD - Run the code with "mvn compile exec:java". This runs successfully.
> # Generate a standalone jar with the command "mvn clean package". This will generate required jar files in target folder.
> # THE BAD - Run the java jar file with "java -jar .\target\TestCamelMail-1.0-SNAPSHOT-jar-with-dependencies.jar". It fails with "java.lang.NullPointerException"
