How to stop log4j2 load class in exception stack?

Log4j2 will load class when print exception stack trace, but it will use the incorrect class loader(org.eclipse.jetty.webapp.WebAppClassLoader, extends URLClassLoader, load class synchronized) to load the class generated by aop (such as sun.reflect.GeneratedMethodAccessor<\digit>, only can load by DelegateClassLoader), and it can never load successfully.
Here is the exception stack trace in my service:

When massive exceptions occurred suddenly, worker thread will blocked on the log4j2 class loader load the GeneratedMethodAccessor<\digit>.
Here is my worker thread stack locked on the method loadClass:

This issue is caused by the class loading that happens while formatting "extended stack traces", which appears as ThrowableProxy.toExtendedStackTrace in your example.
You can disable extended stack traces by adding alwaysWriteExceptions="false" to your PatternLayout (and then adding your own exception formatter, such as %ex, instead), e.g.:
<PatternLayout pattern="%d{ISO8601}{GMT} %m%n%ex" alwaysWriteExceptions="false"/>
I have verified that this fixes the problem for me.
Note that not only does this problem cause locking, it can also cause poor performance due to the JAR unzipping that happens inside e.g. Tomcat's classloader.

what are the cause for the above exceptions? Any quick solutions?

The ClassCastException looks like https://issues.apache.org/jira/browse/CASSANDRA-6462 which was fixed in 2.0.4.
I would suggest upgrading to the latest version and trying again.

The Docs say, "Use this (nodetool cleanup) command to remove unwanted data after adding a new node to the cluster."

could not initialize class org.apache.xerces.jaxp.datatype.xmlgregoriancalendar

I am using web services(a custom/tailor made service for the component) to send and receive information. The request is being formed properly and I am also getting a response. However, during the the mapping of the response to actual DTO, I am getting the following error:
could not initialize class org.apache.xerces.jaxp.datatype.xmlgregoriancalendar
There are some calednar date form in the response, but I am not sure, why it is not able to initialize xmlgregoriancalendar class. I run it on my local with stubs, and it give me no problems at all.
any adivse would be helpful...Thanks in advance

I also got this error: NoClassDefFoundError: Could not initialize class org.apache.xerces.jaxp.datatype.XMLGregorianCalendarImpl
Here is how I fixed it. Add in weblogic.xml this line:
{prefer-web-inf-classes}true{/prefer-web-inf-classes}
By default it's false.
This fix tells me there are jar version conflicts. But I have no idea exactly which jars in what folder that cause the conflicts.

Setting up Titan and Cassandra - Could not instantiate storage manager class

I've set up cassandra server (Datastax community edition) and it's running fine.
My cassandra.yaml has the following settings:
seeds: "127.0.0.1"
storage_port: 7000
rpc_port: 9160
When I do this in gremlin shell:
conf = new BaseConfiguration();
conf.setProperty("storage.backend","cassandra");
conf.setProperty("storage.hostname","127.0.0.1");
conf.setProperty("storage.port",9160);
and,
g= TitanFactory.open(conf);
I get this error:

What am I doing wrong?

I faced the same issue. solution is compatible version check. I downloaded the latest version of cassandra and the error is gone.

GWT NoSuchElementException with HTMLPanel and addAndReplaceElement method

Here some explanations.
If my HTML page contains :
<div id="cancel_date">
<h3 id="cancel_date_title"></h3>
<table align="center">
<tr>
<td id="cancel_date_labelDetailService"></td>
<td id="cancel_date_detailService"></td>
</tr>
</table>
</div>
If my code contains
HTMLPanel container = HTMLPanel.wrap(Document.get().getElementById("cancel_date"));
public void init(){
container.add(getMyWidget(), "cancel_date_detailService");
}
public void reload(){
container.addAndReplaceElement(getService(), "cancel_date_detailService");
}
The first time I load my page, I initialize it with the method init(). The second time and after, I call the method reload().
The first time I call the method reload(), everything works fine. But after, I have a NoSuchElementException like this :

I use GWT 2.4.0
Thanks a lot for help!!!

As its name implies, addAndReplaceElement find the element and replaces it with the given widget. Once you called addAndReplaceElement once for an element, that one element is gone, so the second call obviously won't find it, resulting in the NoSuchElementException you're seeing.
If you ever want to replace your widget with another, then you need to wrap it in an element (i.e. call add instead of addAndReplaceElement), and use remove to remove the previous widget.

Hard to say without a look at your getService() method, but my best guess is that after you call reload() the 1st time the element it's looking for is being replaced. Every other time, the block to be replaced no longer exists, throwing the exception.
