I am writing a Debugger prototype for processing.org and need to get local variables at breakpoints. I am using StackFrame.visibleVariables() but get an AbsentInformationException. What could be the reason for missing local variable information on some methods. The methods I'm seeing this on are neither native nor abstract.
Code is here: https://github.com/martinleopold/DebugMode
