Hi In the latest version of Hudson, which we are running, they added boolean expression support when tying a job to a slave/label. The expression language uses parenthesis. So does our slave names. This has caused some job configurations to fail, e.g. when using the string "minerva.apache.org (Ubuntu)" (claiming this is an invalid expression). I've opened an issue in the Hudson JIRA to see if parenthesis in slave names are now invalid. If so, we might have to rename our slaves. In the short term, I'll keep an eye on any further problems in our setup caused by this (I've fixed a few cases so far).
