Netty client clean multipart tmp data

Question

I'm using VertX http client, which uses netty under hood. When requests with large parameters are being sent, tmp files are generated in /tmp/ : Attr_[timestamp]_[parameterName].att, for example Attr_456456132456431_username.att (which is, for example, 80 KB size)

Requests work fine, but that files are never deleted. It can be done by hand, but I'm looking for a proper solution. Is there any way to make netty (or vertx) delete such tmp files?

Netty itself will not create such files, so it will either be vertx ( I am not aware vertx is doing this either) or something else.

these files are generated by io.netty.handler.codec.http.multipart.DiskAttribute.java, to avoid generating these files, set "useDisk" to false in DefaultHttpDataFactory.java when you init your param decoder
