Log4J2 AppenderLoggingException NoSuchMethodError StackLocatorUtil.getCurrentStackTrace()

Question

As soon as an exception/error occurs and is supposed to be logged, I get the following error/stack trace:

org.apache.logging.log4j.core.appender.AppenderLoggingException: java.lang.NoSuchMethodError: 'java.util.Deque org.apache.logging.log4j.util.StackLocatorUtil.getCurrentStackTrace()'

the next at is whatever called Logger#fatal/error(String,Throwable)

Java 11, Log4J 2.17.2 (-core and -api), project built using Gradle. removing Multi-Release: true from build.gradle doesn't seem to fix the issue (only adds the, to be expected, Reflection.getCallerClass() warning)

What am I missing?

Please provide enough code so others can better understand or reproduce the problem. – Noto

Answer 1

Turns out a library had the dependency Log4J-api 2.17.1 (but not -core), my gradle file specified Log4J-core 2.17.2 so the older -api version overrid the latest one. Apparently, from 2.17.1 to .2, StackLocatorUtil.getCurrentStackTrace()'s return was changed from Stack to Deque.

Dang! Just got caught by this one - updated lib to 2.17.2 and all is well again! – Callan

Answer 2

Looks like the missing method 'org.apache.logging.log4j.util.StackLocatorUtil.getCurrentStackTrace()' is in the log4j-api jar and is called by the AppenderControl class from log4j-core jar.

One possible issue may be that you have both jars on "compile classpath" but only the log4j-core on "runtime classpath". Make sure your gradle configuration does not use the log4j-api as a "compile only" dependency.

Toxicogenic

yes and no. local dependency that had only -api but an older version. The method is present in both versions, but with a different signature (return value). Found it out JUST before you commented – Farmyard
