In step 3, thread-B initialized parameterClasses as an array of null.
Then in step 4, thread-A couldn't find validateId method because
parameterClasses was incorrect.

If you thought that this problem was depends on the configuration, I say "No".
Like I said, this exception didn't occur when I accessed with a browser.
In other words, configuration was correct and this problem didn't occur
when ValidatorAction was accessed by single thread.

I putted a whole stack trace. The information was chipped off at line 627.
But we can suppose the real reason by followings.

A) ValidatorException was thrown because NoSuchMethodException was catched at
line 626.
B) NoSuchMethodException was thrown because parameterClasses was incorrect.
   We can see it in the stack trace.
   "FieldChecks.validateId(java.lang.Object, null, null, null, null, null)"
                                             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
