Looking at the source for RtfDestinationFontTable, I'm guessing the call to
getEnvironmentVariables returned null. This code is taken from 2.0.8-ish.
private Properties getEnvironmentVariables() throws Throwable {
Properties environmentVariables = new Properties();
String operatingSystem =
System.getProperty("os.name").toLowerCase();
Runtime runtime = Runtime.getRuntime();
Process process = null;
if (operatingSystem.indexOf("windows 95") > -1
|| operatingSystem.indexOf("windows 98") > -1
|| operatingSystem.indexOf("me") > -1) {
process = runtime.exec("command.com /c set");
} else if ((operatingSystem.indexOf("nt") > -1)
|| (operatingSystem.indexOf("windows 2000") >
-1)
|| (operatingSystem.indexOf("windows xp") > -1)
|| (operatingSystem.indexOf("windows 2003") >
-1)) {
process = runtime.exec("cmd.exe /c set");
} else {
process = runtime.exec("env");
}
BufferedReader environmentStream = new BufferedReader(new
InputStreamReader(process.getInputStream()));
String inputLine = "";
int idx = -1;
while ((inputLine = environmentStream.readLine()) != null) {
idx = inputLine.indexOf('=');
environmentVariables.setProperty(inputLine.substring(0,
idx),
inputLine.substring(idx + 1));
}
return environmentVariables;
}
Because this is a version of windows unrecognised by the code, it'll call
"env", which isn't going to get very far. The parsing code here will return an
empty properties object, so the call to getProperty( "SystemRoot" ) will return
a null string. When that null is later used in string concatenation: Boom.
The RTF code needs to be updated to support windows 7. It probably already
has. What version of iText are you using?
