I am using a third-party API which internally uses a custom logger based on
log4j. Replacing the log4j with log4j-over-slf4j doesn't help as one of the
method is not present in the log4j-over-slf4j.

Can't share much of the trace as data sharing policy:

Caused by: java.lang.NoSuchMethodError:
org.apache.log4j.Logger.getParent()Lorg/apache/log4j/Category;

Verified the same in codebase of log4j-over-slf4j and this method getParent()
is not present in the jar.

Whereas for log4j v 1.2.17, this is present.

  public final Category getParent()
  {
    return this.parent;
  }
