Solved. I have made a modification to cocos-js, namely:
cocos2d-js-v3.1\tools\cocos2d-console\plugins\project_compile\build_web\__init__.py
The line
child = subprocess.Popen(commands, stderr=subprocess.PIPE)
changed to
child = subprocess.Popen(commands, stderr=subprocess.PIPE, shell=True)
As it was mentioned here: http://www.bogotobogo.com/python/python_subprocess_module.php
The reason is following: it seams that with shell command the process is run on top of intermediate shell which inherit all envrionment variables, while without it uses unknown own (or run without?). And without environment it checkes default paths (i.e., “system32”), where dummy “java.exe” exists.
Verified with “ant”, which is inside my OS “system variables”:

PS: also it is recomended to run “call” instead of “Popen” on subprocess… however in sourcecode the “call” is “popen(…).wait()”
