I wonder what 1 million lines of COBOL translated to Java looks like.
Let us stop and give some caring thoughts to the people who will maintain that code base.

Seems like they manually construct an IR of the source system, then translate the IR to Java Code.
Automatically transpiling COBOL code to Java will lose all possibility of maintenance moving forward. So it is not considered in the first place, nor it is what they need. They need a semi-auto REWRITE of their legacy system, not just target it to Java.
even if it $100 millions, it seems a successful project , given DoD mentioned potential savings of $25 millions/year

All valuable existing business rules have been preserved in the modernized system, while development, test, and production environments were migrated to AWS providing flexibility at reduced cost.

Certainly there are cobol to jvm bytecode options and I'm sure they see some use. One other option I haven't seen yet is cobol to an intermediate DSL in Java that legacy developers could use and code with little trouble, Jobol if you will. This doesn't exist that I know of.
You need to find that Cobol developper, that can work at your office, that will still works for at least the next 10 years, that won't ask a ton of cash because he expect to keep a similar salary as he did before, that is actually competent, etc...
In the other hands, you got 10 000 unemployed java developer that get out of school in less than 500 km around your office, every year, that will do the job nicely for a pretty cheap salary because it's their first job.
