A DESCRIPTION OF THE PROBLEM :
we have recently updated our java from java-11-openjdk|11.0.15.0-150000.3.80.1|x86_64 to java-11-openjdk|11.0.16.0-150000.3.83.1|x86_64. After this we found that our certificated imported in cacerts file under /usr/lib64/jvm/java-11-openjdk-11/lib/security/cacerts disappeared because of which our system failed to work and we again had to re-import the certificate.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Have java version java-11-openjdk|11.0.15.0-150000.3.80.1|x86_64 installed on your system

Import a certificate to cacerts keystore with below command.

keytool -import -trustcacerts -alias acdns -file /usr/sap/SSLCerts/Certs/certificatefile.pem -keystore /usr/lib64/jvm/java-11-openjdk-11/lib/security/cacerts

Update java version to java-11-openjdk|11.0.16.0-150000.3.83.1|x86_64

check the cacerts file to see if the imported certificate is present.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
after update it should not remove this manully imported certificate.
ACTUAL -
after java update it is removing the manually imported certificate
