How does this affect the dependencies on the embedded container?

@nbaars What happened to these jsp files in the new WebGoat.

I stumble upon this incompatibility because I was precompiling the jsp with Jetty JSPC (latest version). I assume this would be the same error when visiting the page with the latest container.

I do not suspect that removing the semicolon would create any backward compatibility problem. I can see imports that just like this one : https://github.com/WebGoat/WebGoat-Legacy/blob/master/src/main/webapp/reportBug.jsp#L3

I am not sure to understand the question about the new WebGoat .. Are you talking about WebGoat 7?
I did not ran into any problem compiling it as-is.
