org.springframework.beans.factory.BeanDefinitionStoreException Failed to read candidate component class

Question

I've read similar post but still cannot resolve this problem. I am using JDK 8 and Spring 5. So it's not due to version issue.

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: file [G:\githome\product-aggregation\target\classes\com\roger\product\ipc\viewobject\product\MultiUnitVO.class]; nested exception is java.lang.ArrayIndexOutOfBoundsException: 90

It's like this. I developed a maven plugin and included it in my project. This plugin is used to generate fields for specific classes in process-classes phase. To achieve this, I used ASM(version 5.0) to modify classes. Maven dependency like this:

<dependencies>
<dependency>
  <groupId>org.apache.maven</groupId>
  <artifactId>maven-plugin-api</artifactId>
  <version>2.0</version>
</dependency>
<dependency>
  <groupId>com.roger</groupId>
  <artifactId>permission</artifactId>
  <version>1.0-SNAPSHOT</version>
</dependency>
<!-- https://mvnrepository.com/artifact/commons-io/commons-io -->
<dependency>
  <groupId>commons-io</groupId>
  <artifactId>commons-io</artifactId>
  <version>2.6</version>
</dependency>
<dependency>
  <groupId>javassist</groupId>
  <artifactId>javassist</artifactId>
  <version>3.12.1.GA</version>
</dependency>
<dependency>
  <groupId>org.apache.maven.plugin-tools</groupId>
  <artifactId>maven-plugin-annotations</artifactId>
  <version>3.2</version>
  <scope>provided</scope>
</dependency>
<dependency>
  <groupId>org.codehaus.plexus</groupId>
  <artifactId>plexus-utils</artifactId>
  <version>3.0.8</version>
</dependency>
<dependency>
  <groupId>org.ow2.asm</groupId>
  <artifactId>asm</artifactId>
  <version>5.0</version>
</dependency>
<dependency>
  <groupId>org.ow2.asm</groupId>
  <artifactId>asm-tree</artifactId>
  <version>5.0</version>
</dependency>

Then I included it in my project.

 <plugin>
    <groupId>com.roger</groupId>
    <artifactId>authorization-maven-plugin</artifactId>
    <version>1.0-SNAPSHOT</version>
    <executions>
      <execution>
        <id>execution1</id>
        <phase>process-classes</phase>
        <goals>
          <goal>addFieldPermission</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

My project also has indirect dependency on ASM(version 5.0.4). I even upgraded ASM to 5.0.4(same as project), it's still going wrong.

I doubted that it's due to ASM conflict but have no idea how to fix it. Any idea?

EDIT Seems it has problem with the modified class. I debugged ClassPathScanningCandidateComponentProvider(spring-context-5.0.8) and found that exception thrown from line 430 just for the modified resources(as I said I added some fields in them by maven plugin). But I decompiled the modified classes using javap and found it's valid. I guess there is problem with the modified classes but don't know what's it.

As stated in the error log this is clear index out of bound exception.

Guess not. Spring ASM was reading MultiUnitVO class and threw this exception. Not programmatic issue. – Roger.H Feb 19 '19 at 09:11

Finally I got a temp solution. I made the fields public and removed the methods generated and everything goes well.

The generated methods are the root cause. When I keep only the generated fields, Spring Boot started up successfully. Seems javassist 3.12.1.GA might go wrong with JDK 1.8. I will further investigate.
