When running jtreg with -vmoptions, those options are not present in the verbose output from jtreg. This makes it hard to see which VM flags were actually used when running a test.

Below is an example.

/*
* @test
* @run main/othervm TestTest
*/
public class TestTest {
   public static void main(String... args) throws Exception {
       throw new Exception();
   }
}

$ jtreg -nr -va -vmoption:-XX:+PrintGC TestTest.java
