Virtual File System on FileOutpuStrem not work

[marcom1981]

I'm try to create file with simple FileOutpuStrem for temporary file.

The project compile but have a error in cosole:

File file = new File("prova.txt");
file.createNewFile();

FileOutputStream os = new FileOutputStream(file);
os.write("ciao".getBytes());
os.close();

This is the output console:

TFileOutputStream.java:69 Uncaught TypeError: bytecoder.imports.fileoutputstream.open0StringBOOLEAN is not a function
    at C.s3244 (TFileOutputStream.java:69:1)
    at p.s3243 (TFileOutputStream.java:68:1)

This Featere is useful for port code who write temporary file.

File.createTempFile() also non work.
