当我尝试在 Tomcat 8.0.24 上运行 Scada-Lts 时，出现以下错误：
23-Sep-2016 11:03:27.228 INFO [Timer-0] org.apache.catalina.loader.WebappClassLoaderBase.checkStateForResourceLoading Illegal access: this web application instance has been stopped already.

还有很多错误，例如：
WARN 2016-09-23 11:03:17,125 (com.serotonin.mango.view.ViewGraphicLoader.loadViewGraphics:58) - Failed to load image set at C:\Users\xxx\Desktop\GitHubProjects\Scada-LTS\out\artifacts\scadabr_1_1_0_RC_war_exploded\graphics\Weather
java.lang.Exception: Unable to derive image dimensions
有人知道我为什么会收到这些错误吗？
