The following two jdb tests fail when run with the virtual thread wrapper (-Dmain.wrapper=Virtual)

vmTestbase/nsk/jdb/list/list003/list003.java
vmTestbase/nsk/jdb/repeat/repeat001/repeat001.java

The tests expect that the "up" command will print "End of stack" because there are normally no frames above the test's main method. However, nsk.share.MainWrapper introduces more frames above the test's main method, so the tests fail.
