Seth Leger updated LOG4J2-832:
------------------------------
    Attachment: Log4j2UninitializableClassTest.java

This test uses a class whose static initializer always throws java.lang.Error. 
If you try to log the Error stack trace that is generated when you load the 
class, than log4j fails because it is not catching the Error generated when 
reflecting the class.

> ThrowableProxy fails if sun.reflect.misc.Trampoline is in logged stack trace

>             Project: Log4j 2
>          Issue Type: Bug
>          Components: Core
>    Affects Versions: 2.0, 2.0.2
>         Environment: Java 1.7u67 Linux/OSX/Win7, Java 1.7u60 Linux, Java 
> 1.7u25 Linux
>            Reporter: Seth Leger
>            Priority: Blocker
>         Attachments: LOG4J2-832.patch, Log4j2MethodUtilTrampolineTest.java, 
> Log4j2MethodUtilTrampolineTest.java, Log4j2UninitializableClassTest.java, 
> ggregory-log4j2.patch, pom.xml

>
> When the Logger attempts to log a message with an exception stack trace, it 
> uses the ThrowableProxy class to introspect classes in the stack trace frames.
> If the class sun.reflect.misc.Trampoline is in the stack trace, the 
> introspection performed by ThrowableProxy will fail causing a java.lang.Error 
> to be thrown by the Logger call.
> The sun.reflect.misc.Trampoline class is used by the 
> sun.reflect.misc.MethodUtil class to perform reflection-based method 
> invocations. MethodUtil is widely used by libraries to perform method 
> invocations. I've encountered this problem when invoking methods over JMX and 
> inside Jetty.
> I am classifying this as a blocker because it means that any logging 
> statement that is logging a Throwable message containing a MethodUtil-based 
> reflection stack trace can cause a java.lang.Error to be thrown by Log4j2. 
> I will attach a unit test for this failure.
