Upgraded Community Commons Module now getting java compile error

I just upgraded to the latest community commons module in my project and now i'm getting a Java compile error:

[javac] \\Mac\Home\Documents\Mendix\SGMS2-main\javasource\communitycommons\Misc.java:656: error: unreported exception COSVisitorException; must be caught or declared to be thrown     [javac]         overlay.overlay(new HashMap<Integer, String>()).save(baos);     [javac]                                                             ^

Has anyone seen this before?
