#588 WebClient classloading error

[Pavel Tonev]

Hello All,

I use maven for my project with configuration

     <dependency>
    <groupId>htmlunit</groupId>
    <artifactId>htmlunit</artifactId>
    <version>1.13</version>
    <type>jar</type>
</dependency>
<dependency>
            <groupId>net.htmlparser.jericho</groupId>
    <artifactId>jericho-html</artifactId>
    <version>2.4</version>
    <type>jar</type>
</dependency>

On creation of WebClient I receive the stacktrace bellow, the situation is too simple to be described more.
I tried just this: Class.forName("org.mozilla.javascript.Context");

and it throws same exception the problem is here into the classloading but I cannot understand where the problem is.

Exception in thread "main" java.lang.VerifyError: (class: org/mozilla/javascript/optimizer/Codegen, method: getFunctionInitMethodName signature: (Lorg/mozilla/javascript/optimizer/OptFunctionNode;)Ljava/lang/String;) Incompatible argument to function

at com.gargoylesoftware.htmlunit.WebClient.<init>(WebClient.java:194)
at com.gargoylesoftware.htmlunit.WebClient.<init>(WebClient.java:178)

Any Help is appreciated

Dear Pavel,

• Do you use Maven 1 or Maven 2?

• Why don't you try HtmlUnit version 1.14?

Hello,

I use maven2, htmlunit 1.14, jericho-html 2.5 in a project that has class which creates WebClient nothing more. Install the artifact into the maven repository. In another project just use it and this error occurs.
The most interesting is that in the first project there is no problem using this WebClient while using installed artifact via maven repository makes the problem.

Kind Regards,
Pavel Tonev

It worked perfectly for me, here are the steps used, please exactly specify yours in order to isolate the issue.

1- Clear '.m2' from user directory.
2- Maven2: Create a new project "mvn -up archetype:create -DgroupId=com.mycompany.app -DartifactId=my-app"
3- Add the follwing dependencies to pom.xml:
<dependency>
<groupId>htmlunit</groupId>
<artifactId>htmlunit</artifactId>
<version>1.14</version>
<type>jar</type>
</dependency>
<dependency>
<groupId>net.htmlparser.jericho</groupId>
<artifactId>jericho-html</artifactId>
<version>2.4</version>
<type>jar</type>
</dependency>
4- In AppTest, update testApp():

public void testApp() throws Exception {
    System.err.println("Hello");
    Class.forName("org.mozilla.javascript.Context");
    new com.gargoylesoftware.htmlunit.WebClient();
    assertTrue( true );
}

5- 'mvn test' creates no errors.

Please retest and advise.
