Hi,
I am having a problem with compiling the following code:
public class Utils {
private static final char[] HEX_CHARS =
"0123456789abcdef".toCharArray();
public static String toHex(byte[] buf)
{
char[] chars = new char[2 * buf.length];
for (int i = 0; i < buf.length; ++i)
{
chars[2 * i] = HEX_CHARS[(buf[i] & 0xF0) >>> 4];
chars[2 * i + 1] = HEX_CHARS[buf[i] & 0x0F];
}
return new String(chars);
}
}
It results in the following Exception:
[java] com.google.gwt.dev.jjs.InternalCompilerException: Unexpected
error during visit.
