AI says:
The ExceptionInInitializerError you're encountering with Java on ARMv7 is typically a signal that the Java runtime is failing to initialize its cryptographic engine (JCE). The root cause often lies in a misconfiguration or a missing OS dependency, not an issue with your application code.
Here are the most common causes and solutions for this problem on ARM Linux.
🔍 Why This Happens
When you call Cipher.getInstance(), the Java runtime loads its internal JceSecurity class. If this initialization fails for any reason, the environment is considered corrupt for cryptographic operations, leading to the ExceptionInInitializerError you see.
The primary suspects on an ARMv7 system are:
-
Missing or Corrupt Cryptographic Policy Files: The Java runtime needs access to a .policy file that defines allowed cryptographic algorithms. This is a known issue when running Java on custom or minimal ARM Linux environments.
-
Inability to Read the Policy Directory: The error can be thrown if the Java process cannot find or read the directory containing the policy files. This is often a path issue in the runtime environment.
