HotswapAgent not hot swapping the java files

[Pratik Kumar]

HI All,

I am using DCEVM-8u181-installer.jar patched with jdk-8u181-windows-x64.exe.

java -version -XXaltjvm=dcevm gave the following result

java version "1.8.0_181"

Java(TM) SE Runtime Environment (build 1.8.0_181-b13)

Dynamic Code Evolution 64-Bit Server VM (build 25.71-b01-dcevmlight-26, mixed mode)

Apart from this I setup following properties

java.mem=8G

tomcat.generaloptions=-Xmx${java.mem} -Xms${java.mem} -XX:PermSize=300M -XX:MaxPermSize=300M -XX:+UseSerialGC -Xss256K -XX:+DisableExplicitGC -XX:CMSInitiatingOccupancyFraction=75 -XX:+CMSClassUnloadingEnabled -XX:+UseCMSInitiatingOccupancyOnly -XX:+CMSParallelRemarkEnabled -XX:+ParallelRefProcEnabled -XX:+CMSScavengeBeforeRemark  -XX:+PrintGCTimeStamps -XX:+PrintGCDetails -Xloggc:"${HYBRIS_LOG_DIR}/tomcat/java_gc.log" -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Dorg.tanukisoftware.wrapper.WrapperManager.mbean=true -Djava.endorsed.dirs=../lib/endorsed -Dcatalina.base=%CATALINA_BASE% -Dcatalina.home=%CATALINA_HOME% -Dfile.encoding=UTF-8 -Dlog4j.configuration=log4j_init_tomcat.properties -Djava.util.logging.config.file=jdk_logging.properties -Djava.io.tmpdir="${HYBRIS_TEMP_DIR}" -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000

tomcat.debugjavaoptions=-XXaltjvm=dcevm -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,server=y,address=8000,suspend=n -javaagent:${platformhome}/resources/hotswap/hotswap-agent-1.4.0.jar=disablePlugin=Log4j2,disablePlugin=Spring,disablePlugin=Proxy,disablePlugin=AnonymousClassPatch,disablePlugin=ZK,autoHotswap=true

The setup is not hot swapping java code changes. Is there something that I missed?
Please help!

Thanks.
