- in places like src/share/classes/sun/security/provider/PolicyFile.java
  you end up with a sequence of String literal appends which could be merged 
into one:

-                sb.append(principalInfo[i][0] + " " +
-                    "\"" + principalInfo[i][1] + "\"");
+                sb.append(principalInfo[i][0]).append(" \"")
+                    .append(principalInfo[i][1]).append('"');

In cases of only 2 chars, I can imagine, that .append(' ').append('\"') would 
have better performance.
