NumberFormatException after verbose flag propagation

Hi there, I noticed that this commit is breaking a Corretto/JDK test (java/lang/PrivateInvokeTest.java) with the following error:

```
STDERR:

This was discovered when running JDK tests with JTReg using this commit as the latest. I noticed that this repository does not have an issues section -- how could I go about opening up this as an issue?

Thanks.
