Java 11 add .pem to cacerts

Question

I try to equip some corporate JDKs with certificates. For Java 8 it was done like this:

keytool -importcert -file cert.pem -keystore cacerts -storepass changeit -noprompt -alias alias

When I do this with Java 11 it is still working, but I get a warning:

Warnung: Verwenden Sie die Option -cacerts für den Zugriff auf den cacerts Keystore

Translation: Warning: Use the option -cacerts für access to cacerts keystore

But I don't know what to do with -cacerts option.

Answer 1

Just replace -keystore cacerts with -cacerts to avoid this warning. More info.
