Is page cache a part of Java Off heap memory? - java

JVM has on heap and off heap memory.
If a java proc write a file to the disk(not in Direct_IO mode), the os will cache the file in memory as page cache, I'm curious if the page cache is a part of JVM offheap memory?
The background is I'm running a scala Spark job in K8S . It get OOM killed frequently even if I set the memory overhead to 0.2. According to the Spark UI, the peak on-heap mem + off-heap mem is much smaller than the container memory limit. But according to dmesg the java proc take all the memory of the container at the time it was killed.
So I'm wondering if it's page cache who takes the rest of memory and cause the java proc being killed?
According to the SparkUI, the dead executor1 on take 21.1 GiB (on heap) + 142.2 MiB (off heap) memory.
spark ui
But according to dmesg, at the time it was killed, it takes much more memory as SparkUI said.

GraalVM Library is not linking in linux mint

I have built a native image application using (GraalVM 22.1.0) in Mac OS environment and it worked, but when trying to build the same application on linux the gluonfx:links fails, with an error of
undefined reference to Java_com_sun_security_auth_module_UnixSystem_getUnixInfo
undefined reference to JNI_OnLoad_jaas
I thought the problem was the libjaas.a not linking as it was not presented in the log file, so i added <arg>-ljaas</arg> but gave me another error which was /usr/bin/ld: cannot find -ljaas

Thanks all.
I was using an older Kafka version.
I upgraded Kafka in the cluster from kafka_2.12-1.1.0 to the latest stable version kafka_2.12-2.7.0. I also upgraded zookeeper from zookeeper-3.4.6 to apache-zookeeper-3.6.2-bin version.
In addition in the run file I added the following:
#!/bin/ksh
unset CLASSPATH
export CLASSPATH=/d4T/hduser/bigquery-kafka-connect-sink/share/kafka/plugins:$KAFKA_HOME/libs
$KAFKA_HOME/bin/connect-standalone.sh \
/d4T/hduser/bigquery-kafka-connect-sink/etc/connect-standalone.properties \
/d4T/hduser/bigquery-kafka-connect-sink/etc/bigquery-sink.properties
where the first part of CLASSPATH comes from plugins
plugin.path=/d4T/hduser/bigquery-kafka-connect-sink/share/kafka/plugins
This solved the issue

Why do I get "null" and "0" when I print out a text file I just read

I am supposed to print out the information that I just read from a text file and what I actually print is all "null" and zeros.

how solve that exception in java creating bar chart? [duplicate]

Anyone can tell me where can I find the full version of JFreeChart? I downloaded the JCommon and JFreeChart as well (from the sourceforge page), but the JFreeChart contains only the jfreechart-demo.jar, so even if I correctly added the libraries in Eclipse, it doesn't work either...
Many Thanks!
When unpacked, the required JAR files are in the lib directory.

Reading txt file from jar fails but reading image works

I have an issue which has been bothering me for days... I checked similar questions but couldn't find a solution.
I use NetBeans IDE. I build the project jar file i.e "Clock.jar" which contains a "clock" named folder in which some images, a text file and all project classes are found.
The following code for creating an image icon works
return new ImageIcon(getClass().getResource("/clock/button_close.png"));
But the following code for reading the text file fails
InputStream name = getClass().getResourceAsStream("/clock/input.txt");
BufferedReader reader = new BufferedReader(new InputStreamReader(name));
As you may have guessed the NullPointer Exception is thrown meaning probably it couln't locate the file.
But how come the image icon is constructed successfully (by passing it the URL returned from getResource) but the txt file cannot be found (by passing it an input stream from getResourceAsStream).
Thanks in advance, for any answer ( I mean it :) )

Looking at the source again closely, try..
URL url = getClass().getResource("/clock/input.txt");
InputStream name = url.openStream();
I recall that the Class::getResourceAsStream variant deals with paths slightly differently than simply Class::getResource - I am sure it should work for the latter one.
