This patch applies to several methods that deal with filepaths in Dir, File, File::Stat, IO, and Kernel. All of these methods now raise an argument error if a null byte is detected in a path argument. Some of these methods are also slightly refactored, mostly by replacing context.runtime with just runtime where applicable.

Some of these methods are also slightly refactored, mostly by replacing
context.runtimewith justruntimewhere applicable.MRI uses
StringValueCstrextensively for this purpose. In JRubyStringSupport.checkEmbeddedNullsseems to do the same job unless I've missed something.After http://jira.codehaus.org/browse/JRUBY-4828, at least File.read raised a SecurityError with the same message but the current 1.7 branch doesn't seem to have any of these checks.
