** Description changed:
+ [Impact]
+
+ * Scilab does not show console prompt and freezes.
+ * Scilab requires additional fixes to properly work with OpenJDK 11, thus it
needs to be backported to releases that have openjdk-lts as the default-jdk.
+ * The bug was caused by the failure to load modules, which had their service
files removed during build time. The change was introduced in scilab 6.0.1-4,
which started using find to remove all empty files during build time, that
caused some required (although empty) files from the modules to be removed as
well, thus causing scilab to fail to find and load these modules.
+
+
+ [Test Case]
+
+ 1. run scilab-cli
+ 2. verify that it reports missing modules and that it hangs
+ ```
+ $ scilab-cli
+ commons module not found.
+ graphic_objects module not found.
+ ui_data module not found.
+ graph module not found.
+ history_browser module not found.
+ slint module not found.
+ coverage module not found.
+
+ ```
+
+ With the fix applied scilab-cli should load and show a prompt to the user
+ ```
+ $ scilab-cli
Scilab 6.0.2 (May 21 2019, 20:36:16)
+
+ -->
+ ```
+
+
+ [Regression Potential]
+
+ * This change only prevent empty files in scilab source from being
+ removed during build time. No side-effect (except for getting the
+ modules working again) is known.
+
+
+ [Original Report]
Steps to reproduce:
1. Have Ubuntu 18.04.2 LTS installed with all updates
2. Install latest Scilab package (6.0.1-7ubuntu1~18.04)
3. Launch Scilab CLI with `scilab-cli` or `scilab-adv-cli`
Expected results:
* Scilab shows its console prompt
Actual results:
* Scilab does not show console prompt and freezes with the following messages:
```
$ scilab-cli
commons module not found.
graphic_objects module not found.
ui_data module not found.
graph module not found.
history_browser module not found.
slint module not found.
coverage module not found.
```
```
