Subject [jira] Commented: (HARMONY-2899) [drlvm][em64t] VM doesn't support native methods with big number of arguments
Date Fri, 29 Dec 2006 12:22:23 GMT
    [ http://issues.apache.org/jira/browse/HARMONY-2899?page=comments#action_12461361 ] 
Gregory Shimansky commented on HARMONY-2899:

I'm attaching a test which calls a native method with maximum possible number of arguments.
Also all argument types are references which makes native stub even longer. On ia32 this creates
a stub of more than 14k bytes. On x86_64 it doesn't work of course.
