JsonMappingException after latest snapshot build

Just recompiled the server using latest snapshot.

Log file is of these messages when creating report:

2016-12-21 00:32:35  WARN: No content to map due to end-of-input
 at [Source: ; line: 1, column: 1] - JsonMappingException (... < QueryBuilder:401 < *:451 < DataManager:285 < Trips:233 < ...)
2016-12-21 00:32:35  WARN: Can not deserialize instance of java.lang.Class out of START_OBJECT token

and these ones:

2016-12-21 00:43:37  WARN: Can not deserialize instance of java.lang.Class out of START_OBJECT token
 at [Source: {}; line: 1, column: 1] - JsonMappingException (... < QueryBuilder:401 < *:451 < *:302 < DataManager:154 < PermissionsManager:263 < ...)

Any clues?

It doesn't look like your are using official source code. Stack trace doesn't match.

The issue might be fixed. See following commit:

https://github.com/tananaev/traccar/commit/da094cc974c545424c843d44d27711ac014d533d

Thanks. Deserialization is fixed.

However still some warnings for end-of-input.

Here is log from server built with updated official source:

2016-12-21 19:23:12  INFO: Version: 3.9-SNAPSHOT

Should I just ignore the warnings as everything is just works as expected?

I have added check for empty string. Please see if you still have problems.

No warnings.
Thank you.
