        StringBuilderWriter out = new StringBuilderWriter();
        JavaCompiler.CompilationTask task = compiler.getTask(out, bjfm, null, options, Collections.emptyList(), Collections.singletonList(new MemJavaFileObject(className, src)));
        task.call();
        if (bjfm.isEmpty()) {
            throw new JavaShellCompilationException(out.toString());
        }
        final Map<String, byte[]> classMap = bjfm.getClassMap();
        jscl.setClassMap(classMap);
    }
