These warnings have been showing up for a while:
[WARNING] While downloading servletapi:servletapi:2.4
This artifact has been relocated to javax.servlet:servlet-api:2.4.
[WARNING] While downloading xerces:xerces:2.4.0
This artifact has been relocated to xerces:xercesImpl:2.4.0.
The former affects curator, grid, product, webapp/filemgr, and webapp/workflow. The latter affects grid.
Right now it's just annoying, though I suppose it could break things someday, so might as well fix it unless someone has an objection. I have modified pom.xml's to check in.
