    private static String getJavaRuntime() throws IOException {
        final String java = getSystemProperty("java.home") + File.separator + "bin" + File.separator +
                (PlatformManager.isPlatformWindows() ? "java.exe" : "java");
        if (!new File(java).isFile()) {
            throw new IOException("Unable to find suitable java runtime at "+java);
        }
        return java;
    }

What's your <java.home> system property value? Does a file exist at the given location (<java.home>/bin/java)?
