In fact we have a number of open bugs concerning the handling of streams
in exec and java :
[1] Pipe Broken
[2] Exec task may mix the stderr and stdout output while logging it
[3] exec task sometimes inserts extraneous newlines
[4] read on System.in hangs for forked java task

Nicolas,
The change you introduced to address this bug
https://issues.apache.org/bugzilla/show_bug.cgi?id=50960
really breaks my output when running java processes because the
autoflush is flushing at 128 byte boundaries. The log output stream
always writes a line when flush is called.
Here is an example:
[java] 15:53:53 WARN - Package Scanner found duplicates for
package 'org.w3c.dom' with different ver
[java] sions. Files: xom-1.1.jar and xmlbeans-2.3.0.jar

[java] '/Users/conor/wor
[java] k/fedefault/output/dist/lib/xmlbeans-2.3.0.jar'
hum...
I guess that more than a simple "autoflush" we should have something
like an "autoflush-on-end-of-line".
I'll try something.
