问题
I work with the old legacy project and trying to switch it to Java 11. At the moment I am able to compile it successfully, but it crashes when starting.
The project consists of several eclipse plugins modules and final eclipse-repository module which has product file (there is also pom file compiles all modules and creates executable file in target folder of the eclipse-repository module)
Targed definition file is resolved succesfully too and looks like
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?pde version="3.8"?>

I'm using two version of eclipse: the latest 2020-12, and 2019-09 because this is the latest version with BIRT whose is used in our project.
My product file is feature-oriented, so the product file looks like
<product name="Noname" uid="noname" version="1.1.1" useFeatures="true" includeLaunchers="true">
<configIni use="default">

there is plugin in pom file
<build>
<plugins>
<plugin>
<groupId>org.eclipse.tycho</groupId>
<artifactId>tycho-p2-director-plugin</artifactId>
</plugin>
</plugins>
</build>
which creates executable for the product. If I start the executable I'll get "Segmetation fault" When I start it as Run Configuration - Eclipse Application, then it will craches with log
!ENTRY org.eclipse.equinox.launcher 4 0 2021-01-30 12:46:42.659

Unforunatelly, I am not sure that I do everything properly. May be someone could tell me where I'm wrong.
回答1:
It seems to me that I found the root cause of my problem. At least my application can be running without crashing into a Segmentation fault. Unfortunately, it still complains about unresolved dependencies but it's a big step forward.
So, the problem was in
<programArgsLin>-os ${target.os} -ws ${target.ws} -arch ${target.arch} -consoleLog
in my product file.
removing -os ${target.os} -ws ${target.ws} -arch ${target.arch} let the application run.
Thanks @greg-449, you're absolutely right about org.eclipse.pde - it is not a feature which I need.
I've refactored my product and it looks like
...
<launcherArgs>
<programArgs>-consoleLog
</programArgs>
<vmArgs>-Xshare:auto -Declipse.ignoreApp=true -Dosgi.noShutdown=true -Dlogback.configurationFile=log.xml
