      When test a post request with payload with Undertow server using the following handler function, it throws exception.

      public class TestHandler implements HttpHandler{

      @Override
      public void handleRequest(final HttpServerExchange exchange) throws Exception{

          HeaderMap headers = exchange.getRequestHeaders();

         if (headers.contains("content-length"){

             Integer contentLength = Integer.parseInt(headers.get("content-length").getFirst());
             if (contentLength > 0)

      {            byte[] body = new byte[contentLength];           exchange.getInputStream().read(body, 0, contentLength);        }

       

        }

      exchange.getResponseHeaders().put(Headers.CONTENT_TYPE, "text/plain");
      exchange.getResponseSender().send("read input ok");

      }

      }

      When test a post request with payload with Undertow server using the following handler function, it throws exception. public class TestHandler implements HttpHandler{ @Override public void handleRequest(final HttpServerExchange exchange) throws Exception{     HeaderMap headers = exchange.getRequestHeaders();    if (headers.contains("content-length"){        Integer contentLength = Integer.parseInt(headers.get("content-length").getFirst());        if (contentLength > 0) {            byte[] body = new byte[contentLength];           exchange.getInputStream().read(body, 0, contentLength);        }     } exchange.getResponseHeaders().put(Headers.CONTENT_TYPE, "text/plain"); exchange.getResponseSender().send("read input ok"); } }

      This class pulls system property "java.specification.version" and expects the value to be an integer or starts with 1. However on Android, this value is always 0.9. Therefore the code is broken at 

      Integer.parseInt(versionString).

      This bug directly impacts usage of HttpServerExchange.getInputStream().read() function.   

      See error log:
