Description
If the JVM local language is Turkish, which has different upper case for the lower case letter i, the result is a runtime error caused by org.apache.kafka.clients.consumer.OffsetResetStrategy. More specifically an enum constant EARLİEST is generated which does not match EARLIEST (note the dotted capital i).
If the locale for the JVM is explicitly set to en_US, the example runs as expected.
A sample error log is below:
