> ThrowableProxy fails if sun.reflect.misc.Trampoline is in logged stack trace
> ----------------------------------------------------------------------------
>
> Key: LOG4J2-832
> URL: https://issues.apache.org/jira/browse/LOG4J2-832
> Project: Log4j 2
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.0, 2.0.2
> Environment: Java 1.7u60, Java 1.7u25
> Reporter: Seth Leger
> Priority: Blocker
> Attachments: LOG4J2-832.patch, Log4j2MethodUtilTrampolineTest.java,
> Log4j2MethodUtilTrampolineTest.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.
