Simon Steiner commented on XGC-137:
-----------------------------------
What about using RestrictedIO settings:
confBuilder = new FopConfParser(new FileInputStream(conf),
EnvironmentalProfileFactory.createRestrictedIO(conf.getParentFile().toURI(),
rr)).getFopFactoryBuilder();
> FOP Default font cache file mishandled when user has no home directory
> ----------------------------------------------------------------------

> Key: XGC-137
> URL: https://issues.apache.org/jira/browse/XGC-137
> Project: XMLGraphicsCommons
> Issue Type: Bug
> Components: general
> Affects Versions: 2.8, 2.9, main
> Environment: Ubuntu 22.04
> Reporter: Paul Robinson
> Priority: Minor
>
> FontCache.getDefaultCacheFile(boolean forWriting) tries to choose and (if
> necessary) create a .fop directory. It checks to make sure that is writable,
> and if not, users a temporary directory instead. Finally, it then returns a
> File pointing inside the .fop directory.
> This all works, but only when FontCache.getUserHome() returns non-null.
> getUserHome() returns null if a user is configured with a non-existent home
> directory (which just happens to be the default when installing Apache Tomcat
> 9 on Ubuntu, where the home directory is /var/lib/tomcat but it doesn't
> exist, whereas /var/lib/tomcat9 does).
> In this case, it simply returns a new file called ".fop". This means the
> default cache file will be called ".fop" in the current working directory.
> This avoids the check to see whether the directory is writable, and it uses a
> file called .fop instead of a directory called .fop.
> If (as can be the case in Tomcat) the current working directory is not
> writable, then the default cache file cannot be written to leading to an
> exception.
> I think this can be fixed with simple change from this:
> {code:java}
> File userHome = getUserHome();
> if (userHome != null) {
> File fopUserDir = new File(userHome, FOP_USER_DIR);
> {code}
> to this:
> {code:java}
> File userHome = getUserHome();
> File fopUserDir = userHome == null ? new File(FOP_USER_DIR) : new
> File(userHome, FOP_USER_DIR);
> {code}
