The Ross-Tech HEX-NET interface, a product of Vcds Inc., allows for wireless vehicle diagnostics using the VCDS software. Occasionally, users encounter issues launching the HexNet Configuration Utility. This article will address a common error, “java.lang.Error: iconv failed,” and offer potential solutions.
Understanding the “iconv failed” Error in VCDS HexNet Utility
The “iconv failed” error typically arises when the Java-based HexNet Configuration Utility encounters a problem related to character encoding conversion. This often stems from incompatibility between the utility and the operating system’s underlying libraries. The error manifests when attempting to launch the utility, preventing users from configuring their HEX-NET interface.
This error message, specifically referencing “iconv,” indicates a failure in the character set conversion library used by the Java application. Iconv (short for “International Codeset Conversion Library”) is a critical component for handling different character encodings across various systems. When this component fails, the Java Virtual Machine (JVM) running the HexNet Configuration Utility cannot properly interpret necessary data, leading to the observed error. This often happens when trying to list available devices.
Diagnosing the Issue with VCDS HexNet
The error message “Exception in thread “AWT-EventQueue-0″ java.lang.Error: iconv failed” often appears within a larger error log, as seen in the example below:
java -jar /Users/AngryGerman/Desktop/HexNetConfigV1.9.jar
Exception in thread "AWT-EventQueue-0" java.lang.Error: iconv failed
at com.codeminders.hidapi.HIDManager.listDevices(Native Method)
...The stack trace points to HIDManager.listDevices(Native Method), indicating the issue occurs when the utility attempts to enumerate connected devices. The core problem lies in the native library responsible for device communication.
Potential Solutions for “iconv failed” with VCDS
