Here are the license texts:
JRE:
http://java.sun.com/javase/6/jre-6u10-license.txt
JDK:
http://java.sun.com/javase/6/jdk-6u10-license.txt
Part B's are about redistribution. They allow redistribution provided that there are
no modifications.
I also found no trace of "commercial use" in the license texts. But I'll
need to read them thoroughly to check for other possible issues.
