JVM Parameters in java

In remote debugging.

1.      Aem forces the jvm to fork a process.

2.      UseSplitVerifier is required for java 7. (Even to start cq normally w/o debug mode.)

Modify start.bat (or create a debug.bat by modifying start.bat)

if not defined CQ_JVM_OPTS set CQ_JVM_OPTS=-Xmx1024m -XX:MaxPermSize=512M -XX:-UseSplitVerifier -Djava.awt.headless=true
-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=30302

OR

if not defined CQ_JVM_OPTS set CQ_JVM_OPTS=-Xmx1024m -XX:MaxPermSize=512M -XX:-UseSplitVerifier -Djava.awt.headless=true
-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=30303

OR

start "CQ" cmd.exe /K java -Xdebug -Xrunjdwp:transport=dt_socket,server=y,address=30302,suspend=n %CQ_JVM_OPTS% -jar %CQ_JARFILE% %START_OPTS%

Or Run from CMD (from the directory where jar is present)

java -jar cq-publish-p4503.jar -XX:MaxPermSize=512m -Xmx1024m
-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=30305
-Dsling.run.modes=publish

OR

java -jar cq-publish-p4503.jar -XX:MaxPermSize=512m -Xmx1024m
-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=30303
-Dsling.run.modes=publish
