Surprising and inconsistent behavior depending on default locale

[ScottDugas]

Some of the code in the record layer changes behavior based on the default locale of the system.
Most of this does not seem intentional.

[ScottDugas]

One example:

final Optional<LogicalOperator> logicalOperatorOptional = Enums.getIfPresent(LogicalOperator.class, functionName.toUpperCase(Locale.getDefault())).toJavaUtil();

This won't find the enum value with tr_CY

ar_BH can cause anything with String.format and %d to result in ? in the string.
For example:

RecordMetaDataBuilderTest > testSetSubspaceKeyCounter() FAILED
    org.opentest4j.AssertionFailedError: expected: <Subspace key counter must be set to a value greater than its current value (3)> but was: <Subspace key counter must be set to a value greater than its current value (?)>
