Accessing Java Stack to inspect errors

[wbuchanan]

Recently encountered this error code:

 error . . . . . . . . . . . . . . . . . . . . . . . . Return code 5100
        a Java runtime exception occurred;
        This indicates a Java runtime exception occurred inside a
        Java program.  Typically exceptions should be caught by the
        Java program and handled in a graceful way.  This error
        indicates the exception was not handled by the program and
        therefore it is handle by the system.

Has anyone else figured out how to get the stack trace instead of only getting the return code? None of the code analysis/debugging tools I use seem to find any problems with the code, so it'd be helpful if there were a way to inspect this a bit more easily. I've tried to

 set debug on

and

 set trace on

but neither option returns any more information than the error code itself.

It is left up to the Java programmer to trap exceptions and to do something reasonable. Failing that you will get the message that you received, but usually with a stack trace if it is available. The Java code would typically look something like the following...

          
try {
    ...
}
catch(IOException e) {
    SFIToolkit.error("unable to open " + fname + " for writing\n") ;
    SFIToolkit.errorDebug(SFIToolkit.stackTraceToString(e)) ;
}

This would always print a reasonable error message when an IOException occurs, and if debug is on, a stack trace will also be shown.

Hello wbuchanan

I am trying to install the following from the net on Stata 13 (Mac OS)

net install rddensity, from(https://raw.githubusercontent.com/rd...y/master/stata) replace

And this is the website for the command- https://rdpackages.github.io/rddensity/


I get the following error:

net install rddensity, from(https://raw.githubusercontent.com/rd...rddensity/mast
> er/stata) replace
Received fatal alert: protocol_version
https://raw.githubusercontent.com/rd.../master/stata/ either
1) is not a valid URL, or
2) could not be contacted, or
3) is not a Stata download site (has no stata.toc file).

current site is still http://fmwww.bc.edu/repec/bocode/r/
r(5100);


On further inspecting the error message I see the following:

[P] error . . . . . . . . . . . . . . . . . . . . . . . . Return code 5100
a Java runtime exception occurred;
This indicates a Java runtime exception occurred inside a
Java program. Typically exceptions should be caught by the
Java program and handled in a graceful way. This error
indicates the exception was not handled by the program and
therefore it is handle by the system.


Can you please help?

Thanks

Aside from the info above, the only thing I can think of is that you may want to connect with the developers and ask them to create a GitHub pages site to host the source code. That’s why all of the stuff I release via GitHub is accessed from a site that starts with https://wbuchanan.github.io/.
