schemacrawler oracle-plugin not returning SYNONYMS - schemacrawler

Question

I am using schema-crawler to crawl an oracle database (Retrieve Table/Synonym metadata including columns details and foreign keys)
INFO:
-- generated by: SchemaCrawler 16.15.1
-- database: Oracle Oracle Database 12c Standard Edition Release 12.1.0.2.0 - 64bit Production
-- driver: Oracle JDBC driver 19.3.0.0.0
-- JVM system: AdoptOpenJDK OpenJDK 64-Bit Server VM 1.8.0_292-b10
In my POM I have included the oracle plugin
<groupId>us.fatehi</groupId>
<artifactId>schemacrawler-oracle</artifactId>
<version>${schemacrawler.version}</version>
</dependency>
I have set the following in LimitOptionsBuilder & LoadOptions to crawl Schema:
limitOptionsBuilder.tableTypes("TABLE,VIEW,SYNONYM");
limitOptionsBuilder.includeAllSynonyms();
final SchemaCrawlerOptions options = SchemaCrawlerOptionsBuilder.newSchemaCrawlerOptions()
.withLimitOptions(limitOptionsBuilder.toOptions())
.withLoadOptions(loadOptionsBuilder.toOptions());
Catalog cat = SchemaCrawlerUtility.getCatalog(conn, options);
In the Catalog output, I don't see any SYNONYMS. I did some debugging and it seems that the the query that is sent to the database to get the tables is using DBA_TAB_COMMENTS, which unfortunately does not contain SYNONYM information. In oracle synonyms are stored in ALL_SYNONYMS
