Answers

Not exact what you want but as I know in DEBUG MODE, there is an option for primitive Types (int, long,…).

 Switch to Debug perspective.
 In the Variables view click the “menu” item (triangle item before minimize) and select “Java Primitives…”.
 In the Dialog you can choose between Hex view, Ascii view and unsigned (for byte).

Found this, maybe help: Inside the Memory View

On 3.7 (and maybe earlier), go into preferences, type “primitive display” in the filtering area, and choose to display hex values.

Updated answer in Eclipse Kepler 4.3:

In the Debug perspective, the Variables tab will have View Menu (a downward triangle), Minimize (a line), and Maximize (a window) icons in the upper-right corner. Click on View Menu > Java > Java Preferences… to bring up a menu. In this menu select Java > Debug > Primitive Display Options. Check “Display hexadecimal values” and then click OK. You should now see hex values in brackets in the Variables tab.

You can add a Watch Expression:

   StringBuilder sb = new StringBuilder();
    for(byte b: buf) {
      sb.append(String.format("%02x, ", b & 0xff));
    }
    sb.setLength(sb.length() - 2);
    return "[" + sb + "]";

In IntelliJ IDEA 14, displaying of hex values in arrays in debugger can be enabled with Settings → Debugger → Data Views → Java → Show hex values for primitives.
