PROFILE_GET.

data, then the global
- * context is changed to context2 (from this method). Each test validates
that a default read
- * using global context2 then gets no valid results (as expected), and that
a read using
- * original context values in the PROFILE_GET config_overrides argument gets
all expected results.
- *
- * @return context2 - The profiler client configuration context created by
this method.
- * The context2 values are also set in the configuration of the
StellarStatefulExecutor
- * stored in the global variable 'executor'. However, there is no API
for querying the
- * context values from a StellarStatefulExecutor, so we output the
context2 Context object itself,
- * for validation purposes (so that its values can be validated as being
significantly
- * different from the setup() settings).

Review comment:
I will refactor this to a Builder, if not just for consistency. No problem.
