Compiling Device IO

[Dell Green]

Hi Guys,

Just for interest sake i decided to try and compile Device I/O directly on my Raspberry Pi with Arch linux on it, as opposed to using the linaro cross compiler tools.

I used OpenJDK 1.7.0_60 and found a bug in Line 63 in the following java file.

src/se/classes/com/oracle/dio/utils/Configuration.java

/**
     * Returns system property value by the given key using a privileged call.
     *
     * @param key property key
     * @return property value
     */
    public static String getSystemProperty(String key) {
        return AccessController.doPrivileged(new PrivilegedAction<String>() {
                public String run() {
                    return System.getProperty(key);
                }
            });
    }

Javac failed due to the method argument should be final due to anonymous inner class usage. Once i changed this it all compiled great and your samples worked great.

Interestingly when i compiled it previously on my linux box with java 8 on it, it didn’t fail. Not sure why that was.
