问题
I've a web application which sending mail. To perform sending mail I use library which itself based on Apache Commons Email 1.4. When I've used Websphere Liberty 8.5.5.7 everything worked fine, but after I've upgraded to 8.5.5.9 it stopped to work and throwing an exception: javax.mail.NoSuchProviderException the full stack trace I posted at the end of the question.
Again, I've tried to run it on both installations of Websphere Liberty 8.5.5.7 and 8.5.5.9, on first one it works fine on second it's broken. I've tried to look what the difference and it looks that Liberty itself has com.ibm.ws.javax.mail-1.5_1.5.xx.jar package which interfere with Java javax-mail-1.5.2 which used by commons-email 1.4, see its pom.xml here.
After some debugging I've paid attention that:
Liberty 8.5.5.9 uses com.ibm.ws.javax.mail-1.5_1.5.12.jar while Liberty 8.5.5.7 uses com.ibm.ws.javax.mail-1.5_1.5.10.jar possible this is caused to my bug.
So, my question is how can I eliminate the influence of com.ibm.ws.javax.mail which comes together with liberty to make it work or is there another workaround?
Also, where can I submit bug report for Liberty Team?
Update: It looks that Liberty has JavaMail 1.5 feature which can be enabled or disabled, I didn't enable it explicitly, it looks that on of my features enabled it implicitly, this is my features list:
<featureManager>
<feature>jdbc-4.1</feature>
<feature>adminCenter-1.0</feature>
<feature>jndi-1.0</feature>
<feature>localConnector-1.0</feature>
<feature>servlet-3.1</feature>
<feature>ssl-1.0</feature>
<feature>jaxrs-2.0</feature>
<feature>cdi-1.2</feature>
<feature>ejbLite-3.2</feature>
<feature>jsf-2.2</feature>
</featureManager>
Update 2 I've solved this issue by using this article: Overriding a provided API with an alternative version
Just make in your server.xml the following changes:
<application id="" name="Scholar" type="ear" location="scholar.ear">
<classloader delegation="parentLast" />
</application>
And now your libraries will receive higher precedence then Liberty's libraries.

I hit javax.mail.NoSuchProviderException: smtp after updating from Liberty 8.5.5.8 to 8.5.5.9. Adding <feature>javaMail-1.5</feature> to my server.xml worked for me.
