## Example

Here is an example of using sa-jwt.py to generate a JWT token.

```bash

// a generic type that has multiple blank type params.

package main

	"./b"
	"fmt"
)

func main() {
	foo := &b.Foo[string, int]{
		ValueA: "i am a string",
		ValueB: 123,
	}
	if got, want := fmt.Sprintln(foo), "i am a string 123\n"; got != want {
		panic(fmt.Sprintf("got %s, want %s", got, want))
	}

        e.cause instanceof TypeConversionException
        e.cause.message == "Cannot convert string value 'unsupportedEnumValue' to an enum value of type 'org.gradle.execution.commandline.CommandLineTaskConfigurerSpec\$TestEnum' (valid case insensitive values: value1, value2)"
