Recent javac.debuglevel changes to the OpenJDK7 jdk7/build forest have run smack into the ant windows issue regarding commas in command lines: https://issues.apache.org/bugzilla/show_bug.cgi?id=46561
Not all windows users run into this, it depends on whether the bin/ant.bat startup script is used (sh version is fine). I've prepared a webrev for the jaxp and jaxws repositories to just remove the use of javac.debuglevel: http://cr.openjdk.java.net/~ohair/6837665-ant-debuglevel/webrev/ Andrew will likely have a webrev or diff for the langtools repository soon. So you windows users out there watch out, this will probably not work: ant -Djavac.debuglevel=source,lines,vars And may also return a process exit code of 0 after it says "BUILD FAILED" :^( -kto
