Re: [Wrapper-user] Debugging with wrapper

[Chandra P. <cp...@ig...>]

I think wrapper should set ping timeout to zero if -Xdebug and -Xrunjdwp 
.... option is set  for JVMDI supporting VMs. And print out this as 
warning. It should also do the same when -agentlib:jdwp... option is set 
for newer JVMTI supporting VMs. Otherwise, it will always result in 
surprised user.
