F:  Referee's Comments (For Author and Editor)

This is an excellent and very interesting paper. Most of my comments 
address presentation and grammar.

General Comments:
1.	Expand JVM one at the beginning of the paper and then use JVM 
throughout.
2.	Expand SSI one at the beginning of the paper and then use SSI 
throughout.
3.	Change all references to Chapters in the paper to Sections. 
4.	The reference to super-linear speedup in my opinion less than 
helpful (Page 20) as your text implies that you run the 
embarrassingly parallel application with X threads on a single 
machine and then run the run the same application with X 
threads on small cluster. A more realistic test would have been 
to run Y threads on a single machine and NxY threads on N 
machines.

Particular comments:

1.	Change Summary title to Abstract.
2.	Abstract, paragraph 2, what is 10Kloc?
3.	Abstract, last sentence, change "… how we aim at obtaining 
scalability." to "…  how we aim to obtain scalability."
4.	Page 2, last paragraph, change "we enable exploiting 
opportunities for optimizations" to "we provide optimization 
opportunities"
5.	Page 3, change sub-section title to "The Java Virtual Machine"
6.	Page 4, section memory model, paragraph 1, should "integral" 
actually be "integer"?
7.	Figure 2 – this sketch is small and very confusing. I suggest 
it is broken into two figures, with a caption describing the 
basics of each.
8.	Page 6, paragraph 1, The wording "application which are 
concurrent daemons" is confusing and probably incorrect 
terminology.
9.	Page 6, last two paragraphs, the description here for Figure 2 
is confusing to say the least. 
10.	Page 7, object model sub-section, list "key challenges"
11.	Page 7, object model sub-section, change "in the next 
chapter." To "in section X."
12.	Page 7, Thread sub-section, change wording, "To enable a 
scalability gain," to "to provide scalability,"
13.	Page 8, Means to Achieve Scalability sub-section, remove 
"high" from "to obtain high scalability"
14.	Page 8, Means to Achieve Scalability sub-section, 
paragraph 2, list different approaches.
15.	Page 10, first paragraph, change "BACKGROUND Chapter" to 
"Background Section"
16.	Page 12, second last paragraph, add "a" into sentence "if 
such a method is"
17.	Page 12, last paragraph, two lots of "For example"… Looks 
odd and should be changed.
18.	Page 14, thread creation sub-section, first paragraph, 
"subclass" should be hyphenated "sub-class"
19.	Page 14, thread creation sub-section, first paragraph, 
the comment "(see below)" should be changed to be explicit, 
i.e. "(see Fig X)" or "(see sub-section y". 
20.	Figure 8, the legend of dashes/dots does not appear to 
correspond to the dot/dashes in the figure. RMI and Proxy 
Master Relation in the legend appear the same!
21.	Page 18, footnote 12, typo, change "acquired" to 
"acquires"
22.	Page 19, add space between "translate" and "(GA)"
23.	Page 20, citation needed pBOB.
24.	Page 22, reference 1 need a URL or more details of how to 
obtain the info that you refer to, i.e. UCSD Tech Doc #, etc.
