Hello,<p>I have the task to migrate from Braintree API to PayPal REST API and after spending half of the day I was so disappointed of their Java SDK quality that I'm ready to fight this migration in 1st place.<p>Basically:<p>1. Outdated API reference (java code samples) - some classe were replaced but reference still uses them<p>2. deprecated methods in their Java SDK without comments what should be used instead.<p>3. Multiple sdk_config.properties files not supported out of the box (this is very retarded, since they have sandbox)<p>PS: Braintree API is a dream for dev came true, imho
