This very simple serialization/deserialization test fails. This is a regression.

import java.io.*;
public class Enum implements Serializable

public static void main(String[] args)
{
try {
ByteArrayOutputStream outb = new ByteArrayOutputStream();
ObjectOutputStream outs = new ObjectOutputStream(outb);
outs.writeObject(new Enum());
byte[] store = outb.toByteArray();
ByteArrayInputStream inb = new ByteArrayInputStream(store);
ObjectInputStream ins = new ObjectInputStream(inb);
ins.readObject();
}
catch (Throwable e) {
throw new Error(e);
}
}

gij (GNU libgcj) version 4.1.0 20050527 (experimental)
Note: this bug looks similar to a bug I reported against jamvm:
https://sourceforge.net/tracker/?func=detail&atid=543058&aid=1155738&group_id=75148
I paste here the evaluation Robert sent me privately after he fixed it, as it
MIGHT be relevant to gcj too (being a change in classpath).
"
P.S. It was the recent changes made to Classpath.
VMSecurityManager.currentClassLoader() now returns "null" if
checkPermissions(AllPermissions) passes. ObjectInputStream uses this
to resolve a class, and ends up trying to resolve it using the
bootstrap class loader (which fails). By luck SableVM works, because
it doesn't have a complete implementation of VMAccessController, so
checkPermissions(AllPermissions) fails, and currentClassLoader returns
the same as before. I'll report a Classpath/SableVM bug.
