Hi I had the same issue when using SpringBoot 1.5.10.RELEASE with apache ignite 2.4.0.
Was fixed when using telling spring boot to use other (older) version by specifying the following: <properties> <jetty.version>9.2.11.v20150529</jetty.version> </properties> Humphrey -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
