Попытка обновить tomcat для исправления нарушения Ghostcat. Я попытался переопределить версию Tomcat с 8.5.29 через spring-boot-starter-tomcat 1.5.11.RELEASE на Tomcat 8.5.51. Это дает мне NPE на webSocket. Ниже мой build.gradle фрагмент и трассировка ошибок. Кто-нибудь сталкивался с этой проблемой? Любые предложения, как это исправить, пожалуйста?
Build.gradle:
providedRuntime group: 'org.springframework.boot', name: 'spring-boot-starter-tomcat', version: '1.5.11.RELEASE'
compile group: 'org.apache.tomcat.embed', name: 'tomcat-embed-core', version: '8.5.51'
compile group: 'org.apache.tomcat.embed', name: 'tomcat-embed-el', version: '8.5.51'
compile group: 'org.apache.tomcat.embed', name: 'tomcat-embed-websocket', version: '8.5.51'
compile group: 'org.apache.tomcat', name: 'tomcat-annotations-api', version: '8.5.51'
