SSL issues are common while working on enterprise applications, but their debugging is not easy. Mostly due to not having enough information in logs.
For example, you will get an exception like this for various reasons – I/O error: java.security.NoSuchAlgorithmException: Error constructing implementation
.
An exception stack trace may look like this:
com.howtodoinjava.aav.exception.SystemException: I/O error: java.lang.RuntimeException: Unexpected error:
java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty; nested exception is
javax.net.ssl.SSLException: java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException:
the trustAnchors parameter must be non-empty

1. Problem
Well, as I said that there could be N number of reasons for these errors. Some of them may be:
- file not found
- wrong password
- wrong keystore type
- wrong cert locations

2. Solution
To solve this SSL exception, you must get more information that can tell exactly what is going on. To get that information, enable SSL debug logging by passing javax.net.debug=ssl
runtime argument to your server/program.
-Djavax.net.debug=ssl
After passing this flag, you will see extensively detailed logs related to your SSL issue, and mostly It will tell you the exact root cause as well.
Happy Learning !!
