Hmm.  The latest nighly shows that the output to be <body onload="">, as
expected.  So I'll assume that this has been fixed.

As to "${param.onload + ''}" results in "0".  This is actually correct.  JSP 2.0
JFD3 (http://jcp.org/aboutJava/communityprocess/first/jsr152/index3.html)
JSP.2.3.5.1 indicates that the operator +, when applied to null and '', results
in a value 0.  In EL, + is used for additions, not concatenations.
