Hello people

I updated today to spring 5.2.8.RELEASE and started to give error in my mock session for JUNIT

My tdd uses the following configuration:

    <bean class="org.springframework.beans.factory.config.CustomScopeConfigurer">
        <property name="scopes">
            <map>
                <entry key="session">
                    <bean class="org.springframework.context.support.SimpleThreadScope"/>
                </entry>
            </map>
        </property>
    </bean>

in version 5.2.6.RELEASE backwards works without error. Could someone help me how to get around this? Regards

This may potentially be a regression introduced in https://github.com/spring-projects/spring-framework/commit/50a4fdac6e0a670a227941920d3e08c2e1372b4f#diff-0a063fe61d0e0640b8c05f6ad641c486.

Note that we do have some simple tests in place for this (see SimpleThreadScopeTests and simpleThreadScopeTests.xml).

@FernandoFranzini, can you provide a minimal sample application that reproduces the issue you are experiencing?

Comment From: sbrannen

@FernandoFranzini, can you confirm the Java version you are using?

I ask, because we assume the ConcurrentModificationException only occurs on Java 11+.

Comment From: FernandoFranzini

Hi Sam I'm using OracleJDK11. Thanks for the quick response. I'll be using 5.2.6 until .9 comes out. Regards

Comment From: sbrannen

I'm using OracleJDK11.

Thanks for the prompt feedback. That confirms our suspicions.

Comment From: sbrannen

This has been fixed in 5.2.x and will be available in the next snapshots for 5.2.9.

@sbrannen Is this a bug of Java 11+?

Comment From: quaff

Never mind, I found the answer in commit log.
