tools for analyzing java code

[Mads Rasmussen <mads () opencs com br>]

Anyone knows any tools to analyze security problems with java code?

I have come across some, like

Lint4j
http://www.jutils.com/index.html

CodePro Analytix
http://www.instantiations.com/codepro/download.asp

Jtest
http://www.parasoft.com/jsp/products/home.jsp?product=Jtest&itemId=14

Parasoft's Jtest that mainly does coding style analysis but appears to 
have some security checks (50+).

I would like to hear from anyone who has experience with these tools or 
anyone who might know better ways to analyze java code from a security 
perspective.
