title: How to compile an OpenJDK 7 debug build on Ubuntu 11.10
body: <p>Where can I find a simple set of instructions to compile an <a href="http://openjdk.java.net/" rel="nofollow">OpenJDK</a> 7 debug build on Ubuntu 11.10 (Oneiric)? A debug build would make more JVM options available for troubleshooting purposes; for example, <code>WizardMode</code>. The <a href="http://openjdk.java.net/guide/" rel="nofollow">developers' guide</a> and <a href="http://hg.openjdk.java.net/jdk7/build/raw-file/tip/README-builds.html" rel="nofollow">build README</a> have a lot of noise and are hard to follow.</p>
