title: Java 32-bit vs 64-bit compatibility
body: <p>Will Java code built and compiled against a 32-bit JDK into 32-bit byte code work in a 64-bit JVM?  Or does a 64-bit JVM require 64-bit byte code?</p>
  
  <p>To give a little more detail, I have code that was working in a Solaris environment running a 32-bit JVM, but now I'm getting issues after upgrading the JDK and Weblogic Server to 64-bit.</p>
