Actually the outcome is predictable:
monitorenter will obtain objectref on this (aload_0)
* if no other thread has locked the object
* if the object is currently locked by another thread (monitorenter
instruction)
* if the current thread already owns a lock - the lock is released when the
counter
returns to 0
.method static doSort([I)V
aload_0
monitorenter
; sensitive code
monitorexit
...
return
end method
