[jira] [Updated] (DERBY-6287) Don't use reflection to call Java 6 methods in FileUtil

["Knut Anders Hatlen (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/DERBY-6287?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Knut Anders Hatlen updated DERBY-6287:
--------------------------------------

    Attachment: derby-6287-1a.diff

The attached patch makes FileUtil call the Java 6 methods directly. It also removes some unused fields from the Java 7 reflection code in that class.

All regression tests ran cleanly. Tested both on Java 6 and on Java 8.

> The FileUtil class uses reflection to call the following java.io.File methods:
>   setWritable(boolean, boolean)
>   setReadable(boolean, boolean)
>   setExecutable(boolean, boolean)
> Reflection was used because the methods were introduced in Java 6, and the code had to run on older platforms. Now Java 6 is the lowest supported platform, so we can call the methods directly.
