> {quote}
> It is important to note that the Logger returned by one of the getLogger factory methods may be garbage collected at any time if a strong reference to the Logger is not kept.

> However, the only reference to [the {{Logger}} created for package {{org.apache.parquet}}|https://github.com/apache/parquet-mr/blob/apache-parquet-1.7.0/parquet-common/src/main/java/org/apache/parquet/Log.java#L58] goes out of scope outside the static initialization block, and thus is possible to be garbage collected.
