Re: [jdt-debug-dev] JSR 45 status and plugin/debugger documentation

From the JDI information, the source locator knows the (unqualified)
file name, in this case "main.nice". This is in a class pkg.fun, so
from this it can know that the source should be in a directory "pkg".
So it could infer the relative file name "pkg/main.nice". It could
then look for this file the sourcepath.
Isn't this a good default, language independent behaviour?
To elaborate a bit on this, let me quote JSR 45:
- The source path must be set-up to include translated-source directories
- Source must be placed in a directory corresponding to the package
To me, this means that when JDI returns an unqualified source file name,
the debugger should look up the source as a file of that name, in a
subdirectory of the sourcepath entries corresponding to the current package.
I can confirm that jdb in JDK 1.4.1 does just that. This part does not
seem to need to be language dependent.
I'm not saying that there should not be any language-dependent
interaction with the debugger core (I suppose this would be needed for
setting breakpoints anyway). But it would still be nice to have as much
standard behaviour from the debugger as possible, so that code needs not
to be duplicated in many plugins.
