By the looks of it, I'd say that Excelsior Jet is very slow if it can't
find a character set loaded by Charset.forName.

I could potentially make the character set loading lazy (so only if it
is really needed), but I'd need to check if that doesn't break
assumptions elsewhere.

Could you give me the results of running the following as an Excelsior
Jet program:

====
import java.nio.charset.Charset;
import java.util.HashMap;
import java.util.Map;
import java.util.concurrent.TimeUnit;
import java.util.logging.Logger;

public class CharsetLoading {

private static final Logger LOG =
Logger.getLogger(CharsetLoading.class.getName());

public static void main(String[] args) {
long start = System.nanoTime();
LOG.info("Starting");
Map<String, Charset> charsetMap = new HashMap<>();
for (String charsetName : new String[]{"US-ASCII", "UTF-8",
"MS932", "EUC_JP", "Cp737", "Cp437", "Cp850", "Cp865",
"Cp860", "Cp863", "Cp775", "Cp858", "Cp862", "Cp864",
"ISO-8859-1", "ISO-8859-2", "ISO-8859-3", "ISO-8859-4",

"Cp1257", "KOI8_R", "KOI8_U", "Cp1258", "TIS620", "GBK",
"Cp943C", "GB18030" }) {
try {
Charset charset = Charset.forName(charsetName);
LOG.info("Loaded charset " + charsetName);
charsetMap.put(charsetName, charset);
} catch (Exception e) {
LOG.severe("Can't load " + charsetName);
}
}
LOG.info(charsetMap.toString());
long end = System.nanoTime();

long duration = end - start;
LOG.info("Took " + duration + " ns (" +
TimeUnit.NANOSECONDS.toMillis(duration) + " ms)");
}
}

For reference, the output when I run this is on Java 8 update 131 is:
