Description
test/jdk/sun/security/provider/SecureRandom/CommonSeeder.java
This test currently uses reflection to hack into a Field object of a static final field to "non-final". It needs a white-box testing mechanism to replace this reflection hack.
static void setDefaultSeeder(EntropySource es) throws Exception {
Field f = AbstractDrbg.class.getDeclaredField("defaultES");
f.setAccessible(true); // no more private
Field f2 = Field.class.getDeclaredField("modifiers");
f2.setAccessible(true);
f2.setInt(f, f2.getInt(f) - Modifier.FINAL); // no more final
f.set(null, es);
}
