Sometimes GroupDocs.Conversion fails when it tries to get document info

Sometimes GroupDocs.Conversion fails when it tries to get document info. I was having this issue when I was running the application on Tomcat Server, but I was able to reproduce the same issue with a Java class. I attached the class that I used to reproduce the error and the documents.

Class: GetSourceDocumentInfo.java.zip (1.1 KB)
Documents: conversion-error.zip (3.8 MB)
Logs: logs.zip (2.2 KB)
SO: Windows 10
Java version: Oracle 1.8.0_221
Server: Apache Tomcat/9.0.45
Lib: GroupDocs.Conversion 21.10
