DSPs are pretty good discriminators for supposed-portable code. On SHARC for example everything is 32-bits wide (except long double, which is 64). Chars are 32 bits. Bytes are 32 bits. That is, int is 32 bits and sizeof(int) == 1. I imagine that porting Java, where byte is defined as an octet, to this architecture must be a chore.

Yeah, people won't port java to DSPs. There's no point in doing that

Doens't Java runs pretty much everywhere, including smartcards?

Not really Java: https://en.wikipedia.org/wiki/Java_Card#Design

The very limited flavor of Java running on smartcards is pretty far from generic Java.
