I think you are absolutely correct this plant is indeed Syzygium heyneanum (Syn: Eugenia heyneana) from the family Myrtaceae. 

… commonly known as: river plum • Gujarati: જળજાંબુ jalajambu • Hindi: कठजामुन kath-jamun • Kannada: ಸಿಮ್ಪಿ ನೇರಲೆ simpi nerale • Konkani: भेडस bhedas • Marathi: भेडस bhedas, पाण जांबूळ pan-jambul • Oriya: jamkoli • Telugu: చిన్న నేరేడు chinna neredu
The common name in Malayalam is vallamanchi … please validate and help me with it in the native script.

Believe it is now called Syzygium alternans [Pan-Jhambal, Bhedas] – ref: Dr.Almeida’s ‘Flora of Maharashtra’, Vol 2. Sending you some of my photographs taken at my farm.
3 images.

…, the ID is resolved to Syzygium heyneanum
The latest name as per KEW is Syzygium salicifolium (Wight) J.Graham, Cat. Pl. Bombay: 73 (1839).

Syzygium alternans flowering: Please read the heading as ‘Syzygium alternans flowering’

The flowers and leaves especially the tender ones in the last picture reminds me of Rose Apple. I may be wrong though.

… the flowers of both are quite similar but S. cumini is yellowish in centre as seen in my pics.

There are 2 different species ie. first 3 pictures are of Syzygium zeylanicum for sure, and the later 2 pictures could be Syzygium cummii. Please see the difference in the inflorescence itself; one is (first 3 pictures) terminal or axis or terminal leaves and the later is born on old stem. Further, if you have taken the late 2 pictures from any riparian (from stream/river with rocks and all) this would again be another species so please tell me from where you have taken the later 2 pictures.

the first three photos may be Syzygium hemisphericum (Wight) Alston (Syn: Eugenia hemispherica Wight, Ic. t. 525. 1842: Jambosa hemispherica (Wight) Walp.) if it has been collected from locations near to streams or river.
Last two photos belong to Syzygium cumini.

Thank you …, Yes there was a dried stream near by. Thank you for both the IDs and sorry fo rthe mix -up.

If you have shot the last 2 pictures from a stream it is not S.cummini nor S.hemisphericum but S.heyneanum. I am working on the pollination ecology of selected Syzygiums in the WG and this is one among them.

Like Giby, i too think it is not S. cumini. http://davesgarden.com/guides/pf/showimage/26041/

Any key characters differentiating these?

‘Syzygium zeylanicum has white berries’ as per BV Shetty et. al. in Plant resources of W.Ghats and lowlands of Dakshina kannada & Udipi (2002).

It is not true, If that is the case written in that book. Last season I handled lots of fruits of the S. zeylanicum. Further, color other than flowers, is not a valid character for id. By the way, dear …, I was not mentioning it as S. zeylanicum but S heyneanum. Have you mistaken at some point?

Thank you for the lead and useful facts sir, I understood your point of identification.
I just added more information on this thread, if someone like to compare these species.

This is NOT Syzygium jambos

Syzygium species in eFloraofindia (with details/ keys from published papers/ regional floras/ FRLHT/ FOI/ Biotik/ efloras/ books etc., where ever available on net) 

It is Syzygium cuminii

Sir if these are two different varieties then can you tell me its varieties names? and is the flowering fruiting time of these cultivar also different?? beacause Syzigium communi trees and these trees are planted in a single row in my university campus, but all S. communi trees are on fruiting stage now but this Syzigium specie (narrow and elongated leaves) trees are still on flowering now and mostly flowers stamens are shedding. i am sending you its  photo which i captured today. Attachments (1)

now this photo is of Syzigium communi at the same stage but 1 month ago ..I think the number of flowers are also more in Syzigium communi than this unidentified specie of Syzigium. Need experts suggestions. Attachments (1)

can it be Syzigium heyneanum?

Syzygium heyneanum (Duthie) Gamble is a synonym of Syzygium salicifolium (Wight) J.Graham  

I think matches with images at Syzygium salicifolium
