* WW-5666 fix(json): apply the input length limit while reading * WW-5666 fix(core): bound the CSP report body read and make the limit configurable CspReportAction read the submitted report body with a single readLine() and had no limit of its own. Read it up to a limit instead, defaulting to 8192 characters and configurable through struts.csp.report.maxSize. A body above the limit is discarded with a warning rather than processed. The limit is injected when the action is built, before the interceptor stack runs, because withServletRequest is invoked by the servletConfig interceptor ahead of staticParams and params. Values that are not usable as a buffer size are ignored with a warning.
