Cobertura JavaNCSS can't parse hexdecimal floating point literals
-----------------------------------------------------------------
Key: MCOBERTURA-140
URL: http://jira.codehaus.org/browse/MCOBERTURA-140
Project: Maven 2.x Cobertura Plugin
Issue Type: Bug
Affects Versions: 2.4
Reporter: Jörg Prante
Priority: Minor
JavaNCSS can't parse hexdecimal floating point literals.
For more info about exdecimal floating point literals, see also
http://blogs.sun.com/darcy/entry/hexadecimal_floating_point_literals
The reason is possibly a broken Java language grammar in JavaNCSS.
