> JoltTransformJson uses under the hood Jackson to parse JSONs. On heavy multithreading workloads, Jackson can have concurrency problem, as also described in this Stackoverflow thread https://stackoverflow.com/questions/17924865/jsonmappingexception-was-java-lang-arrayindexoutofboundsexception. This can cause all the parsing to fail when this problem occurs.
