Update for TLS 1.0 deprecation not working

With the June.15th TLS 1.0 deprecation, I have upgraded my java runtime to java 8 and upgraded to box java sdk 2.19.0 as instructed, but I'm gettting below error when trying to connect to the testing base url https://api-test.box.com/2.0/"

Error message:

com.box.sdk.BoxAPIResponseException: The API returned an error code [400]

Are there anything I'm missing here ?
