Jersey LoggingFeature Without MaxEntitySize

I'm using Dropwizard with Jersey. I've created a new LoggingFeature to log request/response pairs. The code that instantiates the LoggingFeature is:

environment.jersey().register(new LoggingFeature(
            kivasLogger, Level.INFO, LoggingFeature.Verbosity.PAYLOAD_TEXT,
            null));

Unfortunately, my payloads are large and what's being logged is being appended with ...more..., which is not acceptable for my requirements. I need to log payloads of any size. Can I just replace the above null maxEntitySize with Integer.MAX_VALUE or will that, also, not allow the max entity size to exceed the internal threshold?

Thanks.

After some digging, I arrived at my solution and thought that I would post here to share with others who are encountering this problem.

I found that the LoggingFeature class internally uses a DEFAULT_MAX_ENTITY_SIZE value as the default value of the maxEntitySize constructor parameter. This default value is set if the parameter is not set in the constructor, which it wasn't in my question above. In the current implementation of LoggingFeature, the value of DEFAULT_MAX_ENTITY_SIZE is 8192. The maxEntitySize parameter can be successfully overridden with a value larger than DEFAULT_MAX_ENTITY_SIZE. I am currently using a maxEntitySize value of 1024 * 1024 without any issues, and the ...more... appendage is no longer present.

Note, however, that extremely large values such as Integer.MAX_VALUE that I proposed above may not be able to be used without incurring a NegativeArraySizeException (which happened to me).

So basically, changing my problematic line of code above to:

environment.jersey().register(new LoggingFeature(
        kivasLogger, Level.INFO, LoggingFeature.Verbosity.PAYLOAD_TEXT,
        1024 * 1024));

worked for me, but lines with overly large values like:

environment.jersey().register(new LoggingFeature(
        kivasLogger, Level.INFO, LoggingFeature.Verbosity.PAYLOAD_TEXT,
        Integer.MAX_VALUE));

didn't work for me.
