Tomcat 7 Annotation scanner and JDK 8 with -parameters compiler flag exceptions

I am compiling my classfiles with JDK 8 with the -parameters flag which preserves the parameter names and makes them available via reflection. Tomcat 7 seems to have issues with my class files.

Aug 13, 2014 8:31:32 AM org.apache.catalina.startup.ContextConfig processAnnotationsFile
SEVERE: Unable to process file [/home/rex/apache-tomcat-7.0.54/webapps/ROOT/WEB-INF/classes/mod/test/TestData.class] for annotations

I am using Tomcat 7.0.54 and JDK 8u5 x64 Any assistance will be much appreciated :)

I have got the same problem and I resolved it without upgrading tomcat version as the following:

  1. Changing the jaassist version ( i used the version 3.20.0-GA and i changed it to 3.18.1-GA)

  2. adding some args to maven compiler plugin 

    <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>${plugin.compiler.version}</version>
    <configuration>
        <source>${project.build.javaVersion}</source>
        <target>${project.build.javaVersion}</target>
        <forceJavacCompilerUse>true</forceJavacCompilerUse>
        <fork>true</fork>
        <compilerArgument>-proc:none</compilerArgument>             
    </configuration>
</plugin>

  3. adding the tag metadata-complete="true" to the web.xml

Confirmed to be fixed in Tomcat 7.0.56

See changelog for Tomcat 7.0.56 http://tomcat.apache.org/tomcat-7.0-doc/changelog.html

Also tested this locally and it fixed my problems

That is correct, you have to disable annotation processing, see this question org.apache.tomcat.util.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 15 for more information.
