There is a behavior change in keytool somewhere between JDK 8 and JDK 22.

This keytool command used to work in order to build a p12 file but now it’s attempting to prompt in JDK 22; is there a new flag to use instead?

echo "<CLIENT_SECRET>" | keytool -importpass -storetype pkcs12 -alias "<CLIENT_ID>" -keystore "test.p12" -storepass "<store pass>"

Example:
echo "2222" | keytool -importpass -storetype pkcs12 -alias "1111" -keystore "test.p12" -storepass "mypass"
Enter the password to be stored: Re-enter password: They don't match. Try again
Enter the password to be stored: Re-enter password:

When run in JDK 8

Example:

echo "2222" | /Library/Java/JavaVirtualMachines/jdk-1.8.jdk/Contents/Home/bin/keytool -importpass -storetype pkcs12 -alias "1111" -keystore "test.p12" -storepass "mypass"

No output file is just created properly
