I’m using jakarta.mail to send an email, and when I create the session (through Session.getDefaultInstance) I get the following stacktrace:

java.lang.ClassNotFoundException: com.sun.mail.util.LineInputStream
    at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1353)
    at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1165)

    at jakarta.mail.Session.<init>(Session.java:254)
    at jakarta.mail.Session.getDefaultInstance(Session.java:355)

I don’t know where the reference to com.sun.mail.util is coming from.

I have tried looking for any jar referencing mail in my dependencies and excluded them all except for the Jakarta one, and I’m still getting the exception.
I’m running this on a Tomcat 10, OpenJDK17.
