Here seems for JspRuntimeContext we use the version from javax.servlet.jsp, but for Constants we use the version from jasper-compiler. javax.servlet.jsp is a transitive dependency from jetty jsp, and jasper-compiler is a dependency directly in our pom for hbase-server. We need to find a way to deal with it. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
