Flowers blooming
Fruits developing
Nice, skhan! Those flowers are gorgeous. 
I've got yet to try Malay apple. I have several seedlings growing at the moment, but I know I won't have enough space to accommodate them. :/ I'll probably just trade them or something.
Would it even be worth trying to graft/etc and vigorously prune the tree? I've seen members with grades wax jambu fruiting in large containers, but I'm not sure if it'd be worth the time/space unless I had a huuuuge greenhouse.
I've seen people grow wax jambu in pots but not Malay apple.
Over here Malay Apples seem like its mostly grown from seed, I'm curious to see how much less vigor it would have grafted or as a cutting.
I had two planted, traded one away. It had a huge tap root growing straight down. I only managed to dig out 2 feet of it before it snapped.
I don't think there has been much selection on this from, same like wax jambu gets all the attention. I wish the season longer.
From what i understand is it give you a crap load a fruits for like two weeks and then nothing.
