LongHtmlTest fails with java.lang.AssertionError

[Google Code Exporter]

What steps will reproduce the problem?
1. run the LongHtmlTest with Java assertions enabled. (eg using the -ea JVM 
flag)

What is the expected output? What do you see instead?
The test should pass. (I haven't altered the test or the code).
But instead I get the following stack trace
longHtml1(org.outerj.daisy.diff.html.LongHtmlTest)  Time elapsed: 0.116 sec  
<<< FAILURE!

What version of the product are you using? On what operating system?
v 1.1
MacOSX 10.6.6
Java 1.6.0_24

Please provide any additional information below.
The failing assertion is:
 assert (s.indexOf(' ') < 0 && s.length() > maxNbCharsPerLine);
Only the first part fails.  That is, if I comment out the 
s.indexOf(' ') &&
the assertion succeeds and the test passes.

I'm yet to look into whether the assertion is actually unreasonable or whether 
something needs to be fixed to prevent it happening.
