This looks like the same as bug 51102.

The failure seems to be:
-FAIL dt.setObject( Math ); dt.PUB_OBJECT should be [object Math]. Was [object Math].
+FAIL dt.setObject( Math ); dt.PUB_OBJECT should be [object Math]. Was .

or

-FAIL dt.setObject( THIS ); dt.PUB_OBJECT should be [object DOMWindow]. Was [object DOMWindow].
+FAIL dt.setObject( THIS ); dt.PUB_OBJECT should be [object DOMWindow]. Was .

or

 FAIL dt.setObject( Function ); dt.PUB_OBJECT should be function Function() {
     [native code]
-} (of type function). Was function Function() {
-    [native code]
-} (of type object).
+} (of type function). Was  (of type object).

Something is fishy with the toString on this PUB_OBJECT thing.

[Eric Seidel (no email)]

OK.  So these are the last 3 tests in the ToObject-001.js file:
var THIS = this;

a[i++] = new TestObject(
  "dt.setObject( THIS )",
  "dt.PUB_OBJECT",
  "dt.getObject()",
  "dt.getObject().constructor",
  'this',
  'this.constructor');

a[i++] = new TestObject(
  "dt.setObject( Math )",
  "dt.PUB_OBJECT",
  "dt.getObject()",
  "dt.getObject().constructor",
  'Math',
  'Object');

a[i++] = new TestObject(
  "dt.setObject( Function )",
  "dt.PUB_OBJECT",
  "dt.getObject()",
  "dt.getObject().constructor",
  'Function',
  'Function');

dt is:
var dt = applet.createQAObject("com.netscape.javascript.qa.liveconnect.DataTypeClass");

[Eric Seidel (no email)]

http://trac.webkit.org/browser/trunk/LayoutTests/java/lc3/sources/com/netscape/javascript/qa/liveconnect/DataTypeClass.java

is the java involved in this test.

(and possibly http://trac.webkit.org/browser/trunk/LayoutTests/java/lc3/sources/com/netscape/javascript/qa/lc3/jsobject/JSObject_001.java)

My current theory is that there is some sort of race in the wrapping process.  When we pass the object to java, it must end up being wrapped somehow.  That wrapping might be going wrong or being racy?

[Eric Seidel (no email)]

Java seems to try and use javascript from a specific thread.

Code in

jvalue convertValueToJValue(ExecState* exec, RootObject* rootObject, JSValue value, JavaType javaType, const char* javaClassName)

            // Convert value to a string if the target type is a java.lang.String, and we're not
            // converting from a null.
            if (!result.l && !strcmp(javaClassName, "java.lang.String")) {
                if (!value.isNull()) {
                    UString stringValue = value.toString(exec);
                    JNIEnv* env = getJNIEnv();
                    jobject javaString = env->functions->NewString(env, (const jchar*)stringValue.characters(), stringValue.length());
                    result.l = javaString;
                }
            }

Doesn't seem to be trying to move to that thread.  BUt maybe the JSLock is making sure we aren't competing with that thread anyway?

[Eric Seidel (no email)]

jobject JavaJSObject::convertValueToJObject(JSValue value) const

appears to be how we create the JavaJSObjects in the first place (when we're passing "THIS" in, etc.)
