@vidhyabhushanbahl Please log a support case with the IC package.

@vidhyabhushanbahl , Can you please share the complete stack trace? What is the Java version you are using? This setting has been introduced in Java 1.8u331. Can you please try setting the following JVM property and see if it resolves your issue.

-Djdk.xml.xpathExprGrpLimit=100 -Djdk.xml.xpathExprOpLimit=2000

[vidhyabhushanbahl]

Thanks Sharoon23,

I did make this change and it worked but I didn't update the forum. I was using OpenJDK 11.

Cheers

Can you please share where you made the changes?

@namontemayor , you need to set this argument in JVM arguments while starting the AEM instance.

Hi Team,

I am facing similar issue while creating text/list file in Document Fragment on AEM 6.5

May I know a solution to fix this issue. Any help is appreciated.

Thanks in Advance!

@AnushaAt1 , please check the error.log file in crx-quickstart/logs folder of your AEM installation. If you see the exception specified in the origin then you are facing the same issue. You can solve this issue by setting the following JVM argument while starting AEM

-Djdk.xml.xpathExprGrpLimit=100 -Djdk.xml.xpathExprOpLimit=2000

Hi,

Thanks for the response,

In my local, it was working fine. I am facing issue in our AEM instances. May I know where we have to add the property value. It will be helpful.

AEM version : 6.5.19

@AnushaAt1 , 

In your AEM server start command you need to add the above option

java -Djdk.xml.xpathExprGrpLimit=100 -Djdk.xml.xpathExprOpLimit=2000 <..other options..> -jar cq-quickstart.jar

Hello,

Since the process is new to me, Could you please let me know where I have to add those parameter value in the start script, here is our start script. 

# default JVM options
if [ -z "$CQ_JVM_OPTS" ]; then
CQ_JVM_OPTS='-server -Xmx4G -XX:MaxMetaspaceSize=512m -XX:+UseG1GC -XX:MaxGCPauseMillis=200 -XX:ParallelGCThreads=20 -XX:ConcGCThreads=5 -XX:InitiatingHeapOccupancyPercent=70 -Doak.queryLimitInMemory=500000 -Doak.queryLimitReads=100000 -Dupdate.limit=250000 -Doak.fastQuerySize=true -Djava.awt.headless=true -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/p01/app/aem/sandbox/heapdump_log/`date`.hprof -Djava.io.tmpdir=/p01/app/aem/sandbox/tmp'
fi

# file size limit (ulimit)
if [ -z "$CQ_FILE_SIZE_LIMIT" ]; then
CQ_FILE_SIZE_LIMIT=8192
fi

# ------------------------------------------------------------------------------
# authentication
# ------------------------------------------------------------------------------
# when using oak (crx3) authentication must be configured using the
# Apache Felix JAAS Configuration Factory service via the Web Console

# use jaas.config (legacy: only used for crx2 persistence)
#if [ -z "$CQ_USE_JAAS" ]; then
# CQ_USE_JAAS='true'

Can you also let me know whether this should be done in offline and will restart required after making the change?
