+	Empty "" codebase now behaves as "." codebase
+	* file netx/net/sourceforge/jnlp/Parser.java: introduced CODEBASE constant
+	to avoid duplicated String getAttribute  split to getCleanAttribute, which
+	get the pure attribute, and remaining getAttribute keep adding null in case
+	of empty
+	* file netx/net/sourceforge/jnlp/security/SecurityDialogs.java: added 
+	workaround about possible null codebase
+	* file tests/netx/unit/net/sourceforge/jnlp/ParserTest.java: added test for
+	empty codebase

 	Fixed CacheUtils clearCache method to also clear the Least Recently Used
