No provider for smtp exception using AWS SES

Description

I'm all of a sudden getting the following errors when trying to send email. Some emails send fine, others don't. I have over 1K emails stacked up in my mail tasks

"ERROR","Thread-5152211","11/08/2019","18:28:49","","mail;No provider for smtp;javax.mail.NoSuchProviderException: No provider for smtp

My email config in Lucee is:

this.mailservers =[ {
	  host: 'email-smtp.us-east-1.amazonaws.com'
	, port: 587
	, username: 'xxxxxxxx'
	, password: 'encrypted:xxxxxxxx'
	, ssl: false
	, tls: true
	, lifeTimespan: createTimeSpan(0,0,1,0)
	, idleTimespan: createTimeSpan(0,0,0,10)
}];

When I try to send a test message for this smtp server, Lucee indicates that the task succeeds with the message: "Test mail has been sent successfully using [ email-smtp.us-east-1.amazonaws.com ]." but the message does not get delivered. The undelivered mail does show up in tasks, and fails again when I try to execute the task manually.

An aside, the problem very specifically started on Oct. 2, which may have coincided with my last Lucee update, but I cannot recall the exact date that I updated so I cannot confirm that the update was the problem. Is there a way for me to determine the last time Lucee was updated to determine if the update caused the problem?
