Effective in version 10.2 HotFix 1, the error messages that you encounter during a Salesforce session might differ because of a change in the Salesforce API.

For example, when you reconnect to Salesforce the following error message appears:

[ERROR] Reattempt the Salesforce request [getBatchInfo] due to the error [Server error returned in unknown format].

Previously, for the same scenario the following error message was displayed:

[ERROR] Reattempt the Salesforce request [getBatchInfo] due to the error [input stream can not be null].
