Thanks!  Turns out, this is a known problem with older versions of tomcat.  I don't think any changes in groovy are necessary.

Thanks again!

Hi Blake,

       After asm bumped to 6.0 on 2.4 branch, we run into some issues like
yours. So I have downgraded asm to 5.0.3. Please try the latest version of
2.4 branch:
https://www.jitpack.io/#apache/groovy/GROOVY_2_4_X-SNAPSHOT

         FYI, https://github.com/danielsun1106/try-jitpack

Cheers,
