javax.tools.JavaCompiler compile into byte[]

Question

Is it possible for javax.tools.JavaCompiler to compile a file but return the bytecode into a byte[] and not actually creating a .class file?? My current code:

    DiagnosticCollector<JavaFileObject> diagnostics = new DiagnosticCollector<>();
    JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();
    StandardJavaFileManager fileManager = compiler
            .getStandardFileManager(diagnostics, null, null);
    Iterable<? extends JavaFileObject> compilationUnit = fileManager
            .getJavaFileObjectsFromFiles(Arrays.asList(fileToCompile));
    JavaCompiler.CompilationTask task = compiler
            .getTask(osw, fileManager, diagnostics, null, null, compilationUnit);
    task.call()
    fileToCompile.delete();
    fileManager.close();

In the code above fileToCompile is a File. I also want to replace this File by a byte[] or a InputStream of the .java file to compile. Thanks in advance
