OPA interview utility library produces following parsing errors in a high concurrency environment when many threads (around 100) executed together:

Issue doesn't happen in a 1 thread setting. From tracing the stack, it appears this problem occurs in the method when OPA is in the process of reading the XML list to populate drop down list control options.

------------ java.lang.IllegalArgumentException: Cannot parse value as a number: 1.0


 This can be reproduced by writing a simple program that calls the method using many threads (100 works best) together in one go with a CountDownLatch.

 The following messages will be produced if 100 threads are executed but doesn't happen in a 1 thread setting:

 java.lang.IllegalArgumentException: Cannot parse value as a number: 10.0
