Re: [jruby-user] Re: JRE 7 / JRuby 1.7.13 - fatal error precompiling assets for Rails 3.2.x application

Salut Christian;

Thanks for your observation about the memory allocation. Perhaps that was
the original problem.

No, I didn't move my project from JRuby to nodejs. I just removed
therubyrhino javascript interpreter and now let the precompilation of
assets depend on node.js instead
https://github.com/sstephenson/execjs#readme

I do not understand the mechanics of it all, yet, but this change was
certainly a life-saver.

With no other changes (i.e. no increased memory or anything like that), my
assets now precompile without failure by the JVM.
