Additional context N/A

[sokada1221]

Root cause: cadence-web is getting the list of query types from the exception message. Since message formats are different for Go SDK and Java SDK, the parsing is failing for Java exception messages.

Go exception message:

QueryFailedError{Message: unknown queryType a. KnownQueryTypes=[__stack_trace __open_sessions state2 state]}

Java exception message:

QueryFailedError{Message: java.lang.IllegalArgumentException: Unknown query type: a, knownTypes=[GreetingWorkflow::queryGreeting, GreetingWorkflow::queryGreeting2]
