Tomcat – java.lang.InternalError: name is too long to represent

I’ve got the aforementioned exception  when I was trying to load a jsp page on Tomcat 6 running in a debug mode. Turns out the problem occurs when a jsp page grows big. It’s a known JVM issue described by bugs 39089 and 6294277. Here is how to solve it without touching the jsp.

Open conf/web.xml In your Tomcat install directory and add a supressSmap parameter to the jsp servlet:

<servlet>
 <servlet-name>jsp</servlet-name>
 <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
 ..
 <init-param>
  <param-name>suppressSmap</param-name>
  <param-value>true</param-value>
 </init-param>
 ..
</servlet>
