steps

Configure .jvmopts with a comment at the end of the line:

--add-opens=java.base/java.util=ALL-UNNAMED # A comment

problem

Error: Could not find or load main class #

expectation

Was working previously, since 921efce#diff-64087abe6d4b2df660baa360f5041e2e3c05ed9d406e6d297d13c314c3f3ded5R808 it must be defined on a dedicated line instead:

# A comment
--add-opens=java.base/java.util=ALL-UNNAMED

notes

The workaround is easy, the issue is just to notify the breaking change.
