Refactoring code

To fix the problem, we should ensure that the right-hand side of the compound assignment is explicitly cast to long before being added to longValue. This avoids the implicit narrowing conversion and makes the cast explicit, clarifying the intent and preventing accidental loss of precision. The best way to do this is to cast the result of the right-hand side expression to long before performing the addition. Specifically, in line 30, change:

longValue += event.getDeltaY() * (getScrollPower() * (event.isShiftDown() ? 0.5F : 1F));

to

longValue += (long) (event.getDeltaY() * (getScrollPower() * (event.isShiftDown() ? 0.5F : 1F)));

No new imports or method definitions are required.

To fix the problem, we should remove the use of the insecure AllTrustManager and instead use a proper trust manager that validates certificates. If the intention is to trust a specific self-signed certificate (for example, in a development or controlled environment), the correct approach is to load that certificate into a KeyStore and initialize a TrustManagerFactory with it, as shown in the "good" example in the background section.

Specifically, in createAllTrustedClientSslContext(), instead of using AllTrustManager, we should require the caller to provide an InputStream to a trusted certificate (or a keystore containing trusted certificates), and use a TrustManagerFactory initialized with that keystore. If the method is only for testing, it should be clearly marked as such and not used in production. If it is not needed, it should be removed entirely.

The changes required are:

• Remove the AllTrustManager class.
• Remove or refactor createAllTrustedClientSslContext() so that it does not use an insecure trust manager. Instead, require a trusted certificate or keystore to be provided, and use a TrustManagerFactory initialized with it.
• Update the method to match the secure pattern shown in the background section.

To fix the problem, we should replace the use of RC4 with a secure, modern algorithm such as AES. Specifically:

• Change the default algorithm from RC4 to AES (e.g., "AES/ECB/PKCS5Padding" or, preferably, "AES/GCM/NoPadding" for authenticated encryption).
• Remove the ALG_RC_4 constant and replace it with a secure default, e.g., ALG_AES.
• Ensure that the key is of appropriate length for AES (16, 24, or 32 bytes for AES-128, AES-192, or AES-256).
• Use a proper key specification, such as SecretKeySpec, instead of an anonymous SecretKey implementation.
• If possible, avoid ECB mode and use GCM or CBC with a random IV, but since the code only shows the algorithm string, we will use "AES/ECB/PKCS5Padding" as a minimal fix (not ideal, but better than RC4 and within the shown code).

Required changes:

• Replace ALG_RC_4 with ALG_AES = "AES/ECB/PKCS5Padding".
• Update the default constructor to use ALG_AES.
• Use SecretKeySpec for the key.
• Ensure the key is the correct length (pad or truncate as needed).
• Remove the anonymous SecretKey implementation.
