Even if I write the setting of STRICT_QUOTE_ESCAPING in CATALINA_OPTS in tomcat8.5, it is not reflected.

From about tomcat5.5, when I tried to use quotes in jsp scriptlet, I had to escape. It's a hassle to escape this one by one, so org.apache.jasper.compiler.Parser.STRICT_QUOTE_ESCAPING=false If you set it, you can use it as it is. Reference: http://d.hatena.ne.jp/guangda/20091215/1260836855

In my environment, I added a setting to "CATALINA_OPTS" in 2, but when I set it to tomcat8.5, adding this setting did not work and a 500 error occurred! Looking at the process, it was set as an argument, but it didn't work.

When I suddenly look at the difference in web.xml during the investigation up to tomcat8

  <!--   strictQuoteEscaping When scriptlet expressions are used for        -->
  <!--                       attribute values, should the rules in JSP.1.6  -->
  <!--                       for the escaping of quote characters be        -->
  <!--                       strictly applied? [true]                       -->
  <!--                       The default can be changed with the            -->
  <!--                       org.apache.jasper.compiler.Parser.             -->
  <!--                       STRICT_QUOTE_ESCAPING system property.         -->

from tomcat8.5

  <!--   strictQuoteEscaping When scriptlet expressions are used for        -->
  <!--                       attribute values, should the rules in JSP.1.6  -->
  <!--                       for the escaping of quote characters be        -->
  <!--                       strictly applied? [true]                       -->

?? !! It turns out that the description of this part has disappeared

  <!--                       The default can be changed with the            -->
  <!--                       org.apache.jasper.compiler.Parser.             -->
  <!--                       STRICT_QUOTE_ESCAPING system property.         -->

So after this comment on the web.xml side

<servlet>
  <servlet-name>jsp</servlet-name>
  <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
  ~Abbreviation~
  <init-param>
    <param-name>strictQuoteEscaping</param-name>
    <param-value>false</param-value>
  </init-param>
  ~Abbreviation~
</servlet>

When I added, the 500 error disappeared (゚ д ゚) wow ……

that's all. It seems that no one has stepped on this mine yet, so for the time being.
