Since I have just learnt Harmony for a few time, I wonder whether Harmony(especially the VM) has implemented or has been interested in the features as follows. 1. SUN has proposed Java Isolation for a long while, and related specifications have also been released. Unfortunately I cannot find any support for it in SUN JVM till now. Has Harmony implemented or planned to do that? Or maybe SUN has implemented but I do not know it yet. 2. Does SUN JVM or Harmony support to suspend, serialize and resume the JVM? In other words, a JVM can suspend the execution of itself and bytecodes, transfer the execution status into an image file and resume it later. Assuming the external environments such as file system or network connection still keeps. 3. Does the sandbox support appear as an independent project, or has been integrated in Harmony? Where can I find more documents about the sandbox in Harmony? In general, I want to know whether Harmony planned to be another (open source) implementation of SUN JVM, or has its special features beyond the latter? I am not familiar with both SUN JVM and Harmony, so my question may be naive :) Your kind and patient answers are appreciated. Thanks a lot! Rui Chu
