Since Hudson 1.272 (https://hudson.dev.java.net/nonav/issues/show_bug.cgi?id=2760), can supposedly get stdout/stderr in
addition to failure stack traces. This should probably be displayed along with the failures, to give the developer more
context (diagnostic log messages etc.).
Currently this seems broken: https://hudson.dev.java.net/nonav/issues/show_bug.cgi?id=2839
Since Hudson 1.274 it should be possible to use "?xpath=//errorStackTrace" or similar to limit the amount of data
transferred. (Broken in 1.273.)
Hudson should be fixed in 1.281.
Integrated into 'main-golden', will be available in build *200903170201* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)

Log: #156720: showing stdio from tests as well as stack traces.
Also improving robustness of action; an OW tab is created only if output is actually about to be displayed.
