I was able to fake this out for AWS Lambda with the following:
{code:java}
String oldUserHome = System.getProperty("user.home");
System.setProperty("user.home",
System.getProperty("java.io.tmpdir"));
try {
exporter.exportToFile(book, pageFormat,
tempFile.getAbsolutePath());
} finally {
System.setProperty("user.home", oldUserHome);
}
{code}

When you use the PDFTranscoder, it is not possible to disable the font cache or
change the font cache file:
{code:java}
DefaultConfigurationBuilder cfgBuilder = new DefaultConfigurationBuilder();
Configuration cfg =
cfgBuilder.build(getClass().getResourceAsStream("fop-config.xml"));
PDFTranscoder transcoder = new PDFTranscoder();
transcoder.configure(cfg);
TranscoderInput input = new TranscoderInput(getSVGDocument());
ByteArrayOutputStream output = new ByteArrayOutputStream();
TranscoderOutput transOutput = new TranscoderOutput(output);
transcoder.transcode(input, transOutput);
{code}
This is because when you dive into the guts:
# PDFDocumentGraphics2DConfigurator gets created and configures itself using
the configuration passed to the transcoder.
# A new FontManager is created within PDFDocumentGraphics2DConfigurator, which
DOES NOT use the configuration passed to the transcoder.
# This FontManager is then used in DefaultFontConfigurator, and if there were
any system fonts, they are saved.
# The FontManager at this point is configured to use a relative directory
called ".fop" which ends up being local to a read-only file system.
This is in spite of either use-cache being false, or cache-file pointing to
another location.
The FontManager created within the PDFDocumentGraphics2DConfigurator needs to
get its cache location from the FOP configuration.

I think you use EnvironmentalProfileFactory.createRestrictedIO to disable font
caching
{code:java}
String fopxconf = "";
ResourceResolver cloudResourceResolver =
ResourceResolverFactory.createDefaultResourceResolver();
FopFactoryBuilder confBuilder = new FopConfParser(new
ByteArrayInputStream(fopxconf.getBytes()),
EnvironmentalProfileFactory.createRestrictedIO(new
File(".").toURI(), cloudResourceResolver)).getFopFactoryBuilder();
FopFactory fopFactory = confBuilder.build();
FOUserAgent foUserAgent = fopFactory.newFOUserAgent();
FileOutputStream fos = new FileOutputStream("out.png");
Fop fop = fopFactory.newFop("image/png", foUserAgent, fos);
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer();
Source src = new StreamSource(new ByteArrayInputStream(fo.getBytes()));
Result res = new SAXResult(fop.getDefaultHandler());
transformer.transform(src, res);
fos.close();

FontCache.g{{etUserHome()}} method returns {{null}} if the {{user.home}} system
property is unset or the directory pointed to by it does not exist. The latter
seems to be the case on the AWS Lambda Java runtime.

I know this is an old bug, but I'm wondering what situation can user.home
environment variable be unset? If that only on a specific operating system?
