RollingFile Appender creates .tmp files

[pshivaji-tibco]

When file compression is enabled and triggered (gz or zip) and the program exits before Logback can complete the compression, the .tmp files created.

Logback file:

<configuration scan="true">
<shutdownHook class="ch.qos.logback.core.hook.DefaultShutdownHook"/>
  <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>${BW_LOG_DIR}/test.log</file>
    <!-- <fileNamePattern>${BW_LOG_DIR}/test.log</fileNamePattern> -->
    <append>true</append>
    <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
<!-- rollover daily -->
<fileNamePattern>${BW_LOG_DIR}/test.log.%d{yyyy-MM-dd}.log%i.zip</fileNamePattern>
<!-- each file should be at most 100MB, keep 60 days' worth of history, but at most 1GB -->
<maxFileSize>1KB</maxFileSize>
<maxHistory>0</maxHistory>
<totalSizeCap>1KB</totalSizeCap>
 </rollingPolicy>
 <encoder>
      <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %-5level [%thread] &lt;%X{operationID}&gt; %logger{36} - %msg%n</pattern>
    </encoder>
  </appender>

I tried of using shutdownhook as you can see in the above snippet but still .tmp files are generated. I am using logback-core version 1.2.10.
Please help me out with the above issue.
