We are going to need to update the release notes and/or site for 2.6 to note that the 2.6 is not source compatible with previous releases. I tested going from 2.5 to 2.6 at work and got:
[ERROR] COMPILATION ERROR : [INFO] ------------------------------------------------------------- [ERROR] /E:/vcs/svn/...XYZ..:[155,15] reference to error is ambiguous both method error(org.apache.logging.log4j.Marker,java.lang.String,java.lang.Object) in org.apache.logging.log4j.Logger and method error(java.lang.String,java.lang.Object,java.lang.Object) in org.apache.logging.log4j.Logger match [ERROR] /E:/vcs/svn/...XYZ...:[395,15] reference to trace is ambiguous both method trace(org.apache.logging.log4j.Marker,java.lang.String,java.lang.Object) in org.apache.logging.log4j.Logger and method trace(java.lang.String,java.lang.Object,java.lang.Object) in org.apache.logging.log4j.Logger match [INFO] 2 errors with source code like: public void xyz(final String message, final Throwable t) { ... logger.error(null, message, t); ... logger.trace(null, message, t); ... } Next time, I'll remember to test with a "real" client.
