Whats required to participate in the OpenJDK and Mobile&Embedded Communities?
Nothing but your time and interest! You can visit openjdk.java.net or mobileandembedded.dev.java.net and look around, join mailing-list discussions, download the binaries and file bugs, or take the source to make improvements and/or use it yourself. It’s up to you. You don’t even need a java.net user ID to join the mailing lists. Please let us know if you have any suggestions.
