sun.security.provider.certpath.SunCertPathBuilderException on using trust certificate while migrating to Java SDK 3.3.0 version

Hi,
We are migrating our java sdk version from 2.7 to 3.3. And we have couchbase server version 6.5. While using trust certificate, i am getting below error:
2022-08-04T13:55:11.858+05:30 [APP/PROC/WEB/0] [OUT] 2022-Aug-04 08:25:11.857 WARN [cb-events] c.c.endpoint [correlationId : ] - [com.couchbase.endpoint][EndpointConnectionFailedEvent][322ms] Connect attempt 1 failed because of DecoderException: javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target {“circuitBreaker”:“DISABLED”,“coreId”:“xxxxx”,“remote”:“xyz.com:11207”,“type”:“KV”}

Below is the complete code I am using to create cluster:

String connectionString = "couchbases://xyz.com";
ClusterEnvironment.Builder envBuilder = ClusterEnvironment.builder();

envBuilder.securityConfig(SecurityConfig.enableNativeTls(false).enableTls(true).trustStore(certPath, keyStorePassword, Optional.of(“JKS”))).ioConfig(IoConfig.enableDnsSrv(true));

ClusterEnvironment env = envBuilder.build();
Cluster cluster = Cluster.connect(connectionString,
    ClusterOptions.clusterOptions(bucketName, password).environment(env));
cluster.waitUntilReady(Duration.ofMinutes(1));
try {
  System.out.println("Cluster Connection successfull...................");
  QueryResult result = cluster.query("select \"Hello world\" as greetings");
  System.out.println(result.rowsAsObject());
}catch(Exception ex){
  ex.printStackTrace();
}
cluster.disconnect();
env.shutdown();
