Can't install - failing junit tests

Hi, I've been trying to install Babler on my Mac (Big Sur) today using Java 8 (adoptopenjdk-8) and I've been running into some issues. The first couple issues I was able to solve by by modifying pom.xml, so I will try to describe them here.
Issue one: I was getting an error that com.sun.org.apache.regexp.internal could not be found, so I added this to the pom.xml:
<dependency>
<groupId>javax.xml.parsers</groupId>
<artifactId>aixport</artifactId>
<version>1.3.1</version>
</dependency>
Issue two: I was getting another build failure error that read "The forked VM terminated without saying properly goodbye. VM crash or System.exit called." Originally I was able to solve this by ensuring the plugin version was 2.22.0 in pom.xml:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.22.0</version>
</plugin>
However, I'm getting a similar error again. It looks like some of the tests passed successfully but then some of them crashed. If anyone still monitors this repo, can they see something obvious sticking out in this that I'm not seeing? Is one of the "solutions" I used above code-breaking and I should start over from scratch and try something different?

I also can't get a successful build on Linux. I'm also using Java 8 (using java 8 instead of a later version on both OSes because of the sun.management error but I guess I'm still getting it anyway). Here's the logging information for the Linux error:
