> Hi,
I've created -
1.A custom pattern converter plugin extending LogEventPatternConverter
2.A custom layout plugin extending AbstractStringLayout.
3.A custom pattern parser similar to "PatternParser" class in log4j2.
But, as, I am dealing with throwables and cannot modify log4j2 jar, I need to
plug the custom pattern converter instance in my parser class.
if (alwaysWriteExceptions && !handlesThrowable) {
final LogEventPatternConverter pc =
TestPatternConverter.newInstance();
list.add(new PatternFormatter(pc, FormattingInfo.getDefault()));
}
But, at the startup, it is throwing the following exception -
Caused by: java.lang.ClassCastException: com.test.TestPatternParser cannot be
cast to org.apache.logging.log4j.core.pattern.PatternParser
at
org.apache.logging.log4j.core.layout.PatternLayout.createPatternParser(PatternLayout.java:244)
at
org.apache.logging.log4j.core.layout.PatternLayout$SerializerBuilder.build(PatternLayout.java:375)
... 32 more
Please assist.
