It would be useful if java.lang.Throwable printStackTrace() and fillInStackTrace()
used the extra information provided by SourceDebugExtension [NOTE 1] if that
information is available.

A user writes:

  I'm investigating using SourceDebugExtension for compiling a non-java language,
  Nice: http://nice.sf.net. So far the results are promising, in that jdb reports
  files and line numbers as encoded in the SMAP my compiler generates. So far, so
  good.

  However, if a stack trace is generated, I think the jvm should also try to use
  the info in SourceDebugExtension for the default stratum if available, to report
  the line numbers of the stack locations. I found that it does not. Is there a
  plan to implement this in a future version of the JDK? Should I open a bug
  report in the bug database about this?


[NOTE 1] as implemented in JSR 45 "Debugging Support for Other Languages"

EVALUATION This would require a VM change; in fact, it's solely a VM change. It is not clear whether it's worth doing. ###@###.### 2004-01-07
