can't parse type list

Error message

can't parse type list: ${desc}

What it means

Thrown by the default branch of the descriptor parser in listDesc while walking a JNI type descriptor character by character: the current character is not one of 'Z','B','C','S','I','J','F','D','V','[','L', i.e. the descriptor string (typically a method argument list passed via toTypeList) is malformed at that offset. The offending text is included as ${desc}.

Solutions

1. Inspect the full descriptor string reported in the message and locate the illegal character at the failure offset
2. Fix the producer of the descriptor — usually a typo in a method signature string such as a missing ';' after an L...; class type or an unbalanced '('
3. If the input comes from an external file, correct the signature there and re-run the conversion
