Received fatal alert: handshake_failure when using Groovy HTTPBuilder for server using TLSv1.2 - api

Question

I have a question regarding the use of HTTPBuilder. While using the snippet below to create issues using the JIRA API, I am receive the error below:
The server where the API is hosted uses TLSv1.2 and that seems to be my problem.
Received fatal alert: handshake_failure
Here are some of my costraints/limitations:
The project runs on Java 7
The version of Grails is 2.4.3
I know that upgrading the version of Java helps. However, I am specifically interested in learning about how changing/rewriting HTTPBuilder will help me in solving this issue.
def http = new HTTPBuilder("https://jira.xxxxxxx.com/rest/api/2/issue")
if(projectKey=='Type1')
{
http.request(POST, JSON) { req ->
headers.'Authorization' = 'Basic xxxxxxxxxxxxxxxxxxxxxxxxxx'
headers.'Content-Type' = 'application/json'
body = [
fields: [
project : [
key: projectKey
],
issuetype : [
name: issueType
],
reporter : [
name: reporter
],
assignee : [
name: assignee
],
customfield_1 : [
value:'Some value1'
],
customfield_2 : [
value:'Some value2'
],
summary : summary,
description: description,
labels : labels
]
]
response.success = { resp, json ->
return json.key
}
Any help will be appreciated!!

Have you tried this:
Usage:
TlsHttpBuilder tlsHttpBuilder = new TlsHttpBuilder(['TLSv1',
'TLSv1.1', 'TLSv1.2'])
class TlsHttpBuilder extends HTTPBuilder {
List sslProtocols
TlsHttpBuilder(List sslProtocols) {
super()
this.sslProtocols = sslProtocols
}
protected HttpClient createClient(HttpParams params) {
def sslContext = SSLContext.getInstance("TLS")
sslContext.init(null, null, new SecureRandom())
def sf = new org.apache.http.conn.ssl.SSLSocketFactory(sslContext) {
protected void prepareSocket(final SSLSocket socket) throws IOException {
if (sslProtocols) {
log.debug("Setting protocols: ${sslProtocols}")
socket.setEnabledProtocols(sslProtocols as String[])
}
}
}
def schemeRegistry = SchemeRegistryFactory.createDefault()
schemeRegistry.register(new org.apache.http.conn.scheme.Scheme("https", sf, 443))
new DefaultHttpClient(new PoolingClientConnectionManager(schemeRegistry), params)
}
}
