Hi there,
the other day I was playing around with incubator code from JDK16 and noticed
odd behavior wrt the reuseForks configuration.
In order to compile and run tests, my project needs the jdk.incubator.foreign
module. So I configured it like this:
{code:java}
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<reuseForks>false</reuseForks>
<forkCount>1</forkCount>
<argLine>-Dforeign.restricted=permit
--add-modules=jdk.incubator.foreign</argLine>
</configuration>
</plugin>
{code}
Which results in
{code}
[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-surefire-plugin:3.0.0-M5:test (default-test) on
project de.itemis.mosig.sfrf: Execution default-test of goal
org.apache.maven.plugins:maven-surefire-plugin:3.0.0-M5:test failed:

'de.itemis.mosig.sfrf.AppTest'] resolution failed:
jdk/incubator/foreign/MemoryLayout: jdk.incubator.foreign.MemoryLayout -> [Help
1]
{code}
Whereas setting {{reuseForks}} to {{true}} works.
Please note that the project itself is not modularized, i. e. it does not have
a module-info.java specification (on purpose).
I provided a demo for this over at GitHub:
https://github.com/JanMosigItemis/sfrf
Any thoughts?
