Re: JPackage does very weird things and it doesn't work with SNAP

[Alexey Semenyuk]

Hi Davide,

An app launcher generated by jpackage runs `rpm` and `dpkg` queries to 
detect the package that owns it.
Why does it need to know the name of the package? The app launcher needs 
to locate the corresponding ".cfg" (<app-launcher-name>.cfg) file in the 
app image to read the startup configuration. If you configure jpackage 
to create a package installed in "/usr" tree instead of the default 
"/opt" it will create a different app image layout. This makes it 
impossible to hard-code the location of the ".cfg" file in the app launcher.
Instead, the app launcher finds the ".cfg" file in the list of files of 
the package it belongs to.
When the app launcher is launched, it doesn't know the type of the owner 
package (rpm or deb) or its name; it detects these details at runtime. 
That is why it runs `rpm` and `dpkg` queries at startup.

Try running your app with JPACKAGE_DEBUG env variable set to "true": &> 
env JPACKAGE_DEBUG=true <your-app> ...
It logs the launcher's activity, which can give a clue as to what is 
going on.

Hi there...

I have a JDK23 app that is packaged with jpackage.

I am running this app in Snapcraft.
It works well but I cannot restart it for a very weird problem.

When I try to restart it with a simple code like this:
```
ArrayList<String> cmdOutput = new ArrayList<>();
        try {
            **_ProcessBuilder processBuilder = new 
ProcessBuilder("/bin/sh", "-c", 
"/snap/myappid/bin/myappbinarygeneratedwithjpackage");_**
            Process process = processBuilder.start();
            if (waitForOutput > 0) {
                if (process.waitFor(waitForOutput, 
TimeUnit.MILLISECONDS)) {
                    int exitCode = process.exitValue();
                    log.info("Exit code: {}", exitCode);
                    BufferedReader reader = new BufferedReader(new 
InputStreamReader(process.getInputStream()));
                    String line;
                    while ((line = reader.readLine()) != null) {
                        log.info(line);
                    }
                    BufferedReader errorReader = new 
BufferedReader(new InputStreamReader(process.getErrorStream()));
                    while ((line = errorReader.readLine()) != null) {
                        log.error(line);
                    }
                } else {
                    log.error("The command has exceeded the time limit 
and has been terminated.");
                    process.destroy();
                }
            }
        } catch (Exception e) {
            log.error(e.getMessage());
        }
```

This simple code should run
new ProcessBuilder("/bin/sh", "-c", 
"/snap/myappid/bin/myappbinarygeneratedwithjpackage");

If I execute this code when running native, it works well and it spawn 
another instance of my app.
if I execute this code inside a snap environment, the code return an 
exit code 1 and it return this output:

```

If you look at this, this is the output of the "java" command.
Why my app generated to jpackage returns the output of the java 
command in the snap environment?

Is think that this is a jpackage bug.

I tried running strace to understand what is happening
here’s the log from strace capturing the moment my apps tries to 
restart itself inside the Snap sandbox.

jspawnhelper runs
seems like /snap/fireflyluciferin/4/bin/FireflyLuciferin is started at 
some point sucessfully?
followed by some weird calls to rpm and dpkg (???)
a segfault occurs
from forkstat the dpkg/rpm commands are:

```
child           /snap/fireflyluciferin/4/bin/FireflyLuciferin
                sh -c -- rpm --queryformat '%{NAME}' -qf 
'/snap/fireflyluciferin/4/bin/FireflyLuciferin' 2>/dev/null
 32512   0.004s sh -c -- rpm --queryformat '%{NAME}' -qf 
'/snap/fireflyluciferin/4/bin/FireflyLuciferin' 2>/dev/null
parent          /snap/fireflyluciferin/4/bin/FireflyLuciferin
child           /snap/fireflyluciferin/4/bin/FireflyLuciferin
                sh -c -- dpkg -S 
'/snap/fireflyluciferin/4/bin/FireflyLuciferin' 2>/dev/null
 32512   0.004s sh -c -- dpkg -S 
'/snap/fireflyluciferin/4/bin/FireflyLuciferin' 2>/dev/null
```
the jspawnhelper command is:

/snap/fireflyluciferin/4/lib/runtime/lib/jspawnhelper 23.0.1+11 36:37:39
I tried attaching gdb, but it’s clear that jvm doesn’t like debuggers 
attached. Right from the start it got sigstop handlers invoked, and 
then a segfault in libjvm.

I wrote to the snap devs and they replied this:
```
The jspawnhelper binary does obviously very weird things here, 
including invoking various random package managers it has no relation 
with and even explicitly routing stderr to /dev/null so that you can 
not even debug it properly, there is no way on the snap side to fix 
this broken behavior (and apparently it is also not wanted by the 
creators of jspawnhelper that you debug it at all)

There are plenty of java apps in the store (I maintain one myself) 
that work really well simply using the java -jar ... approach…

I fear you will either have to resort to this or contact the jpackage 
maintainers to get this fixed, I’m sure the snapd team will happily 
work with them to get this sorted.

```


the fact that JPackage runs "rpm commands" when I generated a deb file 
seems very weird...
is there someone interested in fixing issue with JPackage and SNAP?
