---------------------------------------
Summary: JDK21: Crash when using new '_' wildcard preview feature
in test classes
Key: SUREFIRE-2201
URL: https://issues.apache.org/jira/browse/SUREFIRE-2201
Project: Maven Surefire
Issue Type: Bug
Reporter: Tobias Gierke
Attachments: image-2023-10-11-14-43-20-661.png, jdk21-surefire-test.zip
Tested with Eclipse Temurin-21+35 (build 21+35-LTS) and Maven 3.9.1 on Ubuntu
22.04.03 LTS
I've attached a reproducer project, running "mvn test" will trip the crash.

What's interesting about this bug is that my reproducer project also contains a
"Main" class that uses the '_' wildcard as well and compiling this one using
"mvn compile" and then trying to run it using "java" directly leads to the same
crash:
!image-2023-10-11-14-43-20-661.png!
BUT compiling the code manually using "javac"
{code:java}
mvn clean ; mkdir -p target/classes && javac -d target/classes --source 21
--enable-preview src/main/java/test/Main.java {code}
and then running it again with "java"
{code:java}
java --enable-preview -cp target/classes test.Main
{code}
does *NOT* crash ... so this seems to be somehow related to the way Maven uses
the Java compiler.
Please move this issue to maven-compiler-plugin if more appropriate.
