Affects PMD Version:
7.10.0 and 7.11.0
Make sure, to test with the latest PMD version.
Description:
We got reports of PMD analysis blocking the build pipelines. It seems to happen in one particular project using the sonar-pmd plugin which uses PMD 7.10.0. Running with PMD plugin in Intellij (PMD 7.7.0) and running from command line with 7.11.0 and pmd check -t 10 on same code base also results in deadlocks. The source code is a Java Spring Boot application.

Found 1 deadlock.
A heapdump analysis on the hanging threads shows at net.sourceforge.pmd.lang.java.symbols.internal.asm.ParseLock.getFinalStatus:
Thread 1: ClassStub:org/springframework/context/annotation/ComponentScan$Filter
Thread 4: ClassStub:org/springframework/context/annotation/ComponentScan
Further up the stack we see in net.sourceforge.pmd.lang.java.ast.ASTCompilationUnit.acceptVisitor these two files are parsed: ApiApplication.java (thread 4) and `JpaConfiguration.java' (thread 1)
We notice @ComponentScan annotation used in ApiApplication.java and @EnableJpaRepositories annotation used in JpaConfiguration.java.
We notice that @EnableJpaRepositories uses the Filter inner interface from ComponentScan via
import org.springframework.context.annotation.ComponentScan.Filter;
When we remove @EnableJpaRepositories from JpaConfiguration.java and remove the java import of that org.springframework.data.jpa.repository.config.EnableJpaRepositories annotation, we cannot get deadlock situation.
Code Sample demonstrating the issue:
ApiApplication.java:
@SpringBootApplication
@ComponentScan({"io.example.auth", "io.example.api"})
public class ApiApplication {
public static void main(String[] args) {
SpringApplication.run(ApiApplication.class, args);
}
}
JpaConfiguration.java:
@Configuration
@EnableJpaRepositories(repositoryFactoryBeanClass = SomeRepositoryFactoryBean.class, basePackages = "io.example.persistence")
public class JpaConfiguration {
...
}
If needed, we can try to create a small SpringBoot app that triggers the deadlock.
Steps to reproduce:
From cli (note it is running with 10 threads, if running with 1 no deadlock occurs):
/.../pmd-bin-7.11.0/bin/pmd check -t 10 -R /.../PMD-jPinpoint-rules/rulesets/java/jpinpoint-rules.xml -d src/main/java -f text --aux-classpath=target/classes:$(cat classpath.txt) -r java-issues-$(date +"%Y%m%d_%H%M").txt
Need to run multiple times to get deadlock, but happens quite often on machine described below.
To generate classpath.txt:
mvn dependency:build-classpath -Dmdep.outputFile=classpath.txt
Running PMD through: CLI (see above) | Maven (via sonar:sonar) | PMD Intellij Plugin
When running locally in command line on MacOS (Apple M1 Max - Sequoia 15.3.1):
java -version openjdk version "23.0.2" 2025-01-21 OpenJDK Runtime Environment Zulu23.32+11-CA (build 23.0.2+7) OpenJDK 64-Bit Server VM Zulu23.32+11-CA (build 23.0.2+7, mixed mode, sharing)
Same happens with Java 21.
Might be related to #5293.
Can deadlock be caused by use of inner interface/class? E.g. org/springframework/context/annotation/ComponentScan$Filter
