Temporary directory for ManualClosingApacheHttpClient43Engine cannot be configured

[dnb-erik-brangs]

I'm using Resteasy 6.2.14.Final via Wildfly 38.0.1.Final for uploading big files to another web application. I noticed big files are always written to java.io.tmpdir. I read the documentation and thought this could be changed via dev.resteasy.entity.tmpdir. However, it seems that the ManualClosingApacheHttpClient43Engine, which seems to be used in my case, does not use this option.

Are there any plans to change this to allow configuring the temporary directory?
