How to fix Encoded password does not look like BCrypt - spring

Question

I have been all over stack overflow trying to find out why this issue is happening, but cannot find an answer.
This is my setup:
SecurityConfig
#Autowired
private IUserService userService;
#Override
public void configure(final AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userService).passwordEncoder(passwordEncoder());
}
#Override
protected void configure(final HttpSecurity http) throws Exception {
// #formatter:off
http.
authorizeRequests().
antMatchers("/api/**"). // if you want a more explicit mapping here
//anyRequest().
// authenticated().antMatchers("/api/users/**").
permitAll().
and().
httpBasic().
and().
sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).
and().csrf().disable();
// #formatter:on
}
#Bean
public PasswordEncoder passwordEncoder(){
PasswordEncoder encoder = new BCryptPasswordEncoder();
return encoder;
}
UserService create method:
#Override
public User create(User u) {
User newUser = new User();
newUser.setUsername(u.getUsername());
newUser.setEmail(u.getEmail());
newUser.setPhoneNum(u.getPhoneNum());
newUser.setPassword(passwordEncoder.encode(u.getPassword()));
// Add default roles
Role userRole = roleService.findByName("ROLE_USER");
newUser.setRoles(Sets.<Role>newHashSet(userRole));
dao.save(newUser);
return newUser;
}
Note that User implements UserDetails and IUserService implements UserDetailsService.
Based on other articles here is some more information:
I'm not trying to do OAUTH so please don't recommend that i also encode the client secret
I checked my database, its a VARCHAR(68), so I believe there is enough room to store the encoded password.
The database does indeed store the encoded password (i looked and its not plain text)
Here is some DEBUG logs from a request that gets denied:

Also note that this is security for a REST API, not a MVC application

The best way to identify this problem "Encoded password does not look like BCrypt" is setup a break porint in class org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder. And then check the root cause for the warnning.
if (!BCRYPT_PATTERN.matcher(encodedPassword).matches()) {
logger.warn("Encoded password does not look like BCrypt");
return false;
}
