[mitreid-connect] simple-web-app java.lang.OutOfMemoryError

Wed Aug 6 11:02:10 EDT 2014

PermGen space and regular memory space are separate in Java, and Spring on Tomcat *REALLY* likes to use PermGen space with all of its beans. You can increase the allocation as well as set up your garbage collector to handle it differently. Here's a bit on Stack Overflow regarding it:

http://stackoverflow.com/questions/23890861/spring-jpa-permgen-out-of-memory

We've got a number of sites running the OIDC server along side the client (with simple-web-app or derivatives) or other applications, like at https://mitreid.org/ for example, so I know it's possible.

Hello!

I'm trying to build my own instance of openid connect infrastructure based on MITREid Connect implementation.

I have successfully downloaded in installed  OpenID-Connect-Java-Spring-Server (v1.1.8) and ldap-openid-connect-server. Both works fine.

Now I'm struggling with simple-web-app. Each time I'm trying to access this application:
http://localhost:8080/simple-web-app
Tomcat reports the following error:

I'm using following java parameters: -Xms3g -Xmx3g. I suppose that 3g should be enough to compile jsp file...
Is this a bug, or did I miss some step?

I'm using default configuration available in simple-web-app project.

Regards,
Marcin
