ADDITIONAL SYSTEM INFORMATION :
Ubuntu 19.04 (Disco Dingo)
openjdk version "11.0.3" 2019-04-16
OpenJDK Runtime Environment (build 11.0.3+7-Ubuntu-1ubuntu1)
OpenJDK 64-Bit Server VM (build 11.0.3+7-Ubuntu-1ubuntu1, mixed mode, sharing)
A DESCRIPTION OF THE PROBLEM :
When the HTML code, that the webengine is tasked to render contains japanese/sundanese punctuation code points, the code is not correctly rendered, but crashes the WebEngine.
Sample characters: \uA9C1\u1CC0\uA9C2
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
I used netbeans to execute the souce code attached.
1. The project is created by placing the pom.xml into a new subdirectory.
2. Under that directory the secondfile needs to be created as: src/main/java/eu/doppel_helix/dev/jdk/reproducecrash/TestBrowser.java.
3. Open the project with netbeans
4. Run clean and build on it (to initialize dependencies from maven central)
5. Open TestBrowser and run it by invoking "Run file" from the context menu
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Page showing the rendered unicode symbols or "missing character" symbols.
ACTUAL -
Segfault from the JVM. In the source code are two variants. I ran both variants, the hs_err log can be found here (as I could not upload it here):
