如何在代码中查找语义格式错误的参数化类型的位置。 JBoss Weld抛出java.lang.reflect.MalformedParameterizedTypeException

Question

Apparently I have put a malformed parameterized type in my code somewhere, but the location is unknown as my IDE has not generated a warning and the stack trace does not reveal the spot where the error was encountered. Any suggestions on how to proceed would be greatly appreciated. I'm stumped.

UPDATE:

The MalformedParameterizedTypeException is

"Thrown when a semantically malformed parameterized type is encountered by a reflective method that needs to instantiate it. For example, if the number of type arguments to a parameterized type is wrong."

Answer 1

I was waaay off. There was no problem with my code at all. The problem was that my project had a dependency that was not compatible with a JEE module installed on the server.

<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>

    <!--
      scope=compile prevents
      Warning:java: Cannot find annotation method 'max()' in type 'javax.validation.constraints.Size':
          class file for javax.validation.constraints.Size not found
    -->
    <scope>compile</scope>

</dependency>

The problem started when Intellij (but not Maven) began to issue warnings, such as the one above, when compiling. The following change eliminated the MalformedParameterizedTypeException problem but reintroduced the annoying Intellij warning.

<scope>provided</scope>
