I don't know very much about this part of gdb.  However, I can say
that in libgcj we create classes on the fly to represent arrays.  Even
the simplest Java program will create at least one such array (for
String[]):

public class t
{
  public static void main(String[] args)
  {
     System.out.println(args.length);
  }
}

Then compile with:

gcj --main=t -o t t.java


There is at least one longstanding gdb SEGV that happens when trying
to re-run a Java executable.  This happens in most, but not every, gdb
session.

Unfortunately I can't try your patch in the near future.
