Briefly shows how to get the actual clear-text password out of a ConnId's GuardedString

DecodeGuardedString.java

// encrypted password is in encPwd
GuardedString encPwd = ...;

final StringBuilder clearPwd = new StringBuilder();

encPwd.access(new GuardedString.Accessor() {

  @Override
  public void access(final char[] clearChars) {
    clearPwd.append(clearChars);
  }
});

// clear-text password is now in clearPwd.toString()

GuardedString is packed into connid-framework JAR, declared as Maven dependency:

<dependency>
  <groupId>org.connid</groupId>
  <artifactId>connid-framework</artifactId>
  <version>1.3.3</version>
