             Summary: AbstractHttpClientWagon#putFromStream reads entire content to memory
                 Key: WAGON-518
                 URL: https://issues.apache.org/jira/browse/WAGON-518
             Project: Maven Wagon
          Issue Type: Bug
          Components: wagon-http
    Affects Versions: 2.12
            Reporter: Chris Lott


Method putFromSteam in class AbstractHttpClientWagon consumes much memory because it first consumes the input stream argument, THEN transfers what it read.  The code that consumes the stream is in the private class RequestEntityImplementation ctor:
{code:java}
     byte[] bytes = IOUtil.toByteArray( stream );{code}
Please revise it, if possible, to behave more like the superclass StreamWagon's putFromStream method, which does the transfer straight from the input stream.

We are attempting to PUT some 150MB artifacts in a java microservice that runs with rather sharp memory limits.  As a local workaround we increased the JVM's -Xmx argument but that way lies madness.

Thanks in advance for any suggestions or workarounds.
