我在项目中使用log4j 1.2.17时遇到了"StackOverflow"错误。
以下是错误的堆栈跟踪

java.lang.StackOverflowError

        at com.java.oauth.client.JavaOauthWithCertificate.getTokenByCertificate(JavaOauthWithCertificate.java:112)

第42行ReadRequiredConfigurationsToObtainToken中的代码部分是
记录器. debug（验证已开始）
SRE Web服务附加器正在将日志写入数据库。这将调用扩展的AppenderSkeleton类以实现自定义附加器。当代码运行时，执行在此点卡住，并在特定时间后引发错误。
我已经尝试增加JVM的堆栈大小和堆大小，但还没有成功。
下面是在属性文件中设置的log4j配置

log4j.rootLogger=DEBUG, A1, A2, A3

# service will ignore this output, but somebody manually running might be interested
log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=[%d] %-5p %c %x - %m%n

# also log to a file - again probably not monitored in production but might be handy for debugging
log4j.appender.A2=org.apache.log4j.DailyRollingFileAppender
log4j.appender.A2.File=C:\\EnergyTrading\\logs\\debug.log
log4j.appender.A2.DatePattern='.'yyyy-MM-dd
log4j.appender.A2.layout=org.apache.log4j.PatternLayout
log4j.appender.A2.layout.ConversionPattern=[%d] %-5p %c %x - %m%n

#web service appender - directs log messages to 
log4j.appender.A3=com.test.sre.logging.SREWebServiceAppender

Any help on this error would be greatly helpful.
