Still with minimal stack, no interrupt support, etc.

Look up the build directory from the running object.

'osv info threads'
'osv thread apply all' (most useful with 'backtrace')

At present, a single command is available, "setargs".

   scripts/imgedit.py setargs /path/to/image arg0 arg1 arg2...

to set the boot arguments.

Java likes upper case in class file names.

Break long lines

Cuts boot time dramatically

Since we're loading multiple objects, we need to load symbol tables for all
of them.  The base addresses are no longer static (esp. after we started
loading mulitple payloads, so we need to read them from the image).

A new command is added for this: 'osv syms'.  It will try to locate symbol
tables for anything that has been loaded at this stage.

(gdb) osv heap

We no longer put any useful information on the VGA device.

Describe all sections to gdb, so it can resolve data object addresses
correctly.

This avoids problems with multiple jvm versions (for example due to OS
updates)

gives more power and is more maintainable
