Bad expansion of input "$["

What steps will reproduce the problem?
1. Provide a JSONPath like "$[someBranch = 'abc'].someOtherBranch"

What is the expected output? What do you see instead?
In PathUtil.splitPath, the first statement:
        if (!jsonPath.startsWith("$.")) {
            jsonPath = "$." + jsonPath;
        }

is doing an expansion to:
$.$[

It should probably be:
        if (!jsonPath.startsWith("$.") && !jsonPath.startsWith("$[") {
            jsonPath = "$." + jsonPath;
        }

Then it does an expansion from this statement:
        jsonPath = jsonPath.replace("$['","$.['")
                ...;

it expands it to:
$.$.[

What version of the product are you using? On what operating system?
0.5.5
