...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.
As per the discussion Attempting bi-dialect session, assuming Postel's Law holds true on the remote end thread 'webdriver dispatcher' panicked at 'index out of bounds: the len is 0 but the index is 0 this issue was observed with Selenium Client v3.0.0-beta3 which was released on 2016-09-01 14:57:03 -0700.
Simon in a comment mentioned that:
The root cause was a ClassCastException. We now catch that exception, log the thing that we were trying to parse and continue with other attempts to complete the handshake. The fix was available in Selenium Client v3.0.0-beta4.
The most appropriate solution would have been to:

...also implies that the ChromeDriver/Chrome Browser combo you are using is not the recent one as the current implementation of ChromeDriver follows W3C and initial logs are as follows:
Starting ChromeDriver 78.0.3904.70 (edb9c9f3de0247fd912a77b7f6cae7447f6d3ad5-refs/branch-heads/3904@{#800}) on port 9626

Please protect ports used by ChromeDriver and related test frameworks to prevent access by malicious code.

Solution
Ensure that:
- JDK is upgraded to current levels JDK 8u222.
- Selenium is upgraded to current levels Version 3.141.59.
- ChromeDriver is updated to current ChromeDriver v78.0 level.
- Chrome is updated to current Chrome Version 78.0 level. (as per ChromeDriver v78.0 release notes)
- Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
- (WindowsOS only) Use CCleaner tool to wipe off all the OS chores before and after the execution of your Test Suite.
- (LinuxOS only) Free Up and Release the Unused/Cached Memory in Ubuntu/Linux Mint before and after the execution of your Test Suite.
- If your base Web Client version is too old, then uninstall it and install a recent GA and released version of Web Client.
- Take a System Reboot.
- Execute your
@Test as non-root user.
- Always invoke
driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.

Outro
As per this jar-download.com article the createSession() in ProtocolHandshake.java file of Selenium v3.0.1 contained the following:
public Result createSession(HttpClient client, Command command)
throws IOException {
// Avoid serialising the capabilities too many times. Things like profiles are expensive.
Capabilities desired = (Capabilities) command.getParameters().get("desiredCapabilities");
desired = desired == null ? new DesiredCapabilities() : desired;
Capabilities required = (Capabilities) command.getParameters().get("requiredCapabilities");
required = required == null ? new DesiredCapabilities() : required;
String des = new BeanToJsonConverter().convert(desired);
String req = new BeanToJsonConverter().convert(required);
// Assume the remote end obeys the robustness principle.
StringBuilder parameters = new StringBuilder("{");
amendW3CParameters(parameters, des, req);
parameters.append(",");
amendOssParamters(parameters, des, req);
parameters.append("}");
LOG.info("Attempting bi-dialect session, assuming Postel's Law holds true on the remote end");
Optional result = createSession(client, parameters);
// Assume a fragile OSS webdriver implementation
if (!result.isPresent()) {
parameters = new StringBuilder("{");
amendOssParamters(parameters, des, req);
parameters.append("}");
LOG.info("Falling back to original OSS JSON Wire Protocol.");
result = createSession(client, parameters);
