Now, you get Java Runtime version error when using a Java version newer than the minimum requirement. Your Java Runtime is incompatible. Please edit your installation to use the bundled Java Runtime. It happens with Java 18 EA on 1. It also happens with Java 18 EA and Java 17 on 1.
It also happens with Java 17, Java 16 and Java 11 on versions older than 1. It should only block older Java versions, not newer ones. It does not happen when using Java 8 to launch a version that is compatible with Java 7. We need to handle the exception carefully in order to fulfill the communication problem.
First, let us see the possible reasons for the occurrence of java. ConnectException: Connection refused. As client and server involved, both should be in a network like LAN or internet. If it is not present, it will throw an exception on the client-side. If the server is not running. Sometimes a server may be running but not listening on port because of some overridden settings etc. Usually, for security reasons, the Firewall will be there, and if it is disallowing the communication.
By mistake, the wrong port is mentioned in the port or the random port generation number given. Connection string information wrong. Now let us see the ways to fixing the ways of java. Skip to content. Change Language.

The file is not a valid package because it contains OPC relationships. The file is not a valid package because it is missing a manifest or block map, or missing a signature file when the code integrity file is present. The computed hash value of the block does not match the one stored in the block map. The requested byte range is over 4GB when translated to byte range of blocks.
This app failed to launch because of an issue with its license. Please try again in a moment. Provider could not perform the action since the context was acquired as silent. The security token does not have storage space available for an additional container. The key parameters could not be set because the CSP uses fixed parameters. The device that is required by this cryptographic provider is not ready for use. The dictionary attack mitigation is triggered and the provided authorization was ignored by the provider.
The validation of the provided data failed the integrity or signature validation. The security package failed to initialize, and cannot be installed. The security package is not able to marshal the logon buffer, so the logon attempt has failed. The per-message Quality of Protection is not supported by the security package. The message or signature supplied for verification has been altered. The function completed successfully, but must be called again to complete the context.
The function completed successfully, but CompleteToken must be called. The function completed successfully, but both CompleteToken and this function must be called to complete the context. The logon was completed, but no network authority was available. The logon was made using locally known information. The supplied message is incomplete. The signature was not verified. The credentials supplied were not complete, and could not be verified.
The context could not be initialized. Additional information can be returned from the context. The certificate chain was issued by an authority that is not trusted. The client and server cannot communicate, because they do not possess a common algorithm.
The security context could not be established due to a failure in the requested quality of service e. A security context was deleted before the context was completed. This is considered a logon failure. The client is trying to negotiate a context and the server requires user-to-user but didn't send a TGT reply. Unable to accomplish the requested task because the local machine does not have any IP addresses. The supplied credential handle does not match the credential associated with the security context.
The crypto system or checksum function is invalid because a required function is unavailable. The local machine must be a Kerberos KDC domain controller and it is not. The other end of the security negotiation is requires strong crypto but it is not supported on the local machine. Expected to find PA data for a hint of what etype to use, but it was not found. The client certificate does not contain a valid UPN, or does not match the client name in the logon request.
Please contact your administrator. The KDC was unable to generate a referral for the service requested. An unsupported preauthentication mechanism was presented to the Kerberos package. The requested operation cannot be completed. The computer must be trusted for delegation and the current user account must be configured to allow delegation. The system cannot contact a domain controller to service the authentication request.
Please try again later. The smartcard certificate used for authentication has been revoked. Please contact your system administrator. There may be additional information in the event log. An untrusted certificate authority was detected While processing the smartcard certificate used for authentication. The revocation status of the smartcard certificate used for authentication could not be determined.
The smartcard certificate used for authentication was not trusted. The smartcard certificate used for authentication has expired. The Kerberos subsystem encountered an error.
A service for user protocol request was made against a domain controller which does not support service for user. An attempt was made by this server to make a Kerberos constrained delegation request for a target outside of the server's realm.
This is not supported, and indicates a misconfiguration on this server's allowed to delegate to list. The revocation status of the domain controller certificate used for smartcard authentication could not be determined.
There is additional information in the system event log. An untrusted certificate authority was detected while processing the domain controller certificate used for authentication. The domain controller certificate used for smartcard logon has expired. Please contact your system administrator with the contents of your system event log.
The domain controller certificate used for smartcard logon has been revoked. A signature operation must be performed before the user can authenticate. One or more of the parameters passed to the function was invalid. Client policy does not allow credential delegation to target server.
Client policy does not allow credential delegation to target server with NLTM only authentication. The PKU2U protocol encountered an error while attempting to utilize the associated certificates.
The returned buffer is only a fragment of the message. More fragments need to be returned.
