Hello Stephen,

2) How to setup the same environment (for non-java savvy people) with
freely available software (Sun JDK okay). I can figure out how to get JDK

IDEA is available for download at http://www.jetbrains.com/idea
You can use either evaluation license or download an EA build and use free EAP 
licence:

1) a strace (system call trace) of what the JVM is doing during the transfer.

To enable JPDA trace IDEA must be started with the following VM property:
-Didea.debugger.trace="<category>[<space><category>]" where <category> is one of the following:
"SENDS"
"RAW_SENDS"
"RECEIVES"
"RAW_RECEIVES"
"EVENTS"
"REFTYPES"
"OBJREFS"
"ALL"

Examples: -Didea.debugger.trace="SENDS RECEIVES" -Didea.debugger.trace="ALL"
As for the code that needs to be debugged in order to reproduce the problem, 
perhaps Eric will help?

apparent networking bug


To chase this regression down, we need:

1) a strace (system call trace) of what the JVM is doing during the transfer.
Is it writing lots of little buffers?

2) How to setup the same environment (for non-java savvy people) with
freely available software (Sun JDK okay). I can figure out how to get JDK
installed, but how to cause the debugging interaction to occur?
