java.io.IOException: Invalid Keystore format

Question

Does anyone know how to solve this? I tried many things, but none of them worked.

And when I click more details I get this:

at sun.security.provider.         


        

Answer 1

(Re)installing the latest JDK (e.g. Oracle's) fixed it for me.

Prior to installing the latest JDK, when I executed the following command in Terminal.app:

keytool -list -keystore $(/usr/libexec/java_home)/jre/lib/security/cacerts -v

It resulted in:

keytool error: java.io.IOException: Invalid keystore format
java.io.IOException: Invalid keystore format
    at sun.security.provider.JavaKeyStore.engineLoad(JavaKeyStore.java:650)
    at sun.security.provider.JavaKeyStore$JKS.engineLoad(JavaKeyStore.java:55)
    at java.security.KeyStore.load(KeyStore.java:1445)
    at sun.security.tools.keytool.Main.doCommands(Main.java:792)
    at sun.security.tools.keytool.Main.run(Main.java:340)
    at sun.security.tools.keytool.Main.main(Main.java:333)

But, after installing the latest Oracle JDK and restarting Terminal, executing the following command:

keytool -list -keystore $(/usr/libexec/java_home)/jre/lib/security/cacerts -v

Results in:

Enter keystore password:  

Which indicates that the keytool on path can access the keystore.
