Here is another question concerning LuaJava:

I'm currently checking inhowfar LuaJava is "thread-safe" (it
must be - otherwise it would be impossible to script graphi-
cal user interfaces).

For that reason,  I instantiate  a Java Thread object  which
uses a run function from a Lua table (by means of a "helper"
class written in Java which solves some problems arising due
to the way LuaJava tries to handle polymorphism).

Everything works fine (e.g., I can invoke the "run" function
myself)  until I try to "start"  the thread - then I get the
following output

  error: attempt to index a string value
  error: unable to recover; exiting

For illustration purposes,  here is the relevant part  of my
source code:
  public class LuaJava_11 {
    public static Thread newThread (Runnable LuaWrapper) {
      return new Thread(LuaWrapper);

  HelperClass = javaBindClass("LuaJava_11");

  function startThread
    local LuaThread = {
      run = function (self)

    local JavaThrad = HelperClass:newThread(LuaThread);


I've tried lots of variants of this code - but without any

Does anybody have any idea?

Thanks in advance for your help!
