来自 log4j 的 java.lang.IllegalArgumentException

Question

我的客户遇到问题，他已向我发送日志文件。
日志文件包含一些崩溃，如下所示。

log4j:WARN Failed to set property [maxFileSize] to value "10MB". 
java.lang.IllegalArgumentException: object is not an instance of declaring class
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
...

log4j:WARN Failed to set property [file] to value "../logging/serviceContainer2100.log". 
java.lang.IllegalArgumentException: object is not an instance of declaring class
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
...

log4j:WARN Failed to set property [maxBackupIndex] to value "10 ". 
java.lang.IllegalArgumentException: object is not an instance of declaring class
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
...

随附 log4J 配置文件:

# Set root logger level and appenders.
log4j.rootLogger=info, A1, R

# Appender A1
log4j.appender.A1=org.apache.log4j.ConsoleAppender

# Layout for A1
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%d [%t] %-5p %c %x - %m%n

# Appender R
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=log/DependencyAnalyzer.log
log4j.appender.R.MaxFileSize=1000KB
log4j.appender.R.MaxBackupIndex=10

# Layout for R
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%d [%t] %-5p %c %x - %m%n

我尝试用谷歌搜索这个问题，但没有得到任何满意的答复。
谁能建议在哪里进一步深入研究这个问题或者可能的原因是什么？

文件属性值似乎有错误../logging/serviceContainer2100.log比较您的配置文件中的值，请尝试一下 log4j.properties配置文件，可能会给您一些帮助，我只是对文件路径和一些附加程序进行了一些更改以进行测试，但它对我有用，等待您的反馈

# Root logger option
log4j.rootLogger=DEBUG,A1 , A,  R


 # Appender A1
log4j.appender.A1=org.apache.log4j.ConsoleAppender
