I'm using Maven 2.2.1 and getting a heap overflow when trying to
deploy an artifact about 50MB in size. I'm deploying to an Nexus
server (HTTP).
I added "@set MAVEN_OPTS=-Xms128m -Xmx512m" to my mvn.bat and now it is working.
But my question is, why should uploading a file require so much
memory? It's not like it tries to read the whole file into memory, or
does it? If so, that seems kinda dumb.

P.S. Here's the trace:
