There is not much info published yet, but if you google "Lattice Avant" you get some stories about it. What is known: released date H2 2022, so at the end of the year we should hear more about this product. FPGA core size at least 300,000 Logic Cells. That's about all that is known without NDA. Excited, only a few more months to wait.
Surprise, surprise, at least two projects promise java 2 RTL (VHDL, Verilog) conversion suitable for execution on FPGA!
Java2VHDL is currently only experimental but LED blink at least works. The current work seems to support directly only Lattice Diamond tools. Here is a link to the project Java2VHDL. The LED blink and other examples are tested on this tiny board XO2000.

There is another Java converter, called synthesijer, with web and GitHub for project code. This project uses Xilinx evaluation boards as target hardware.
