No, truss does not need microstate accounting enabled in order to work. 
It is the JVM's attempt to turn on microstate accounting that causes the 
problem for truss, not whether it's turned on or off in the first place. 
The promotion of G1 to the default GC in Java9 has caused this issue to 
become more visible as it is the only thing in the JVM that uses the 
(to-be-removed) code in question.

AFAIK Java9 won't be supported on Solaris 9 anyway, so I'm not sure 
there is any benefit in doing that, it's more likely to cause confusion 
than anything else.
