Connection not released in case of error

[DavideD]

ReactiveSessionImpl#reactiveClose() calls super.close:

hibernate-reactive/hibernate-reactive-core/src/main/java/org/hibernate/reactive/session/impl/ReactiveSessionImpl.java

Line 1741 in f02390b

super.close();

The problem is that super.close could throw an exception, for example because threadCheck() can fail.
In that scenario the connection is never released, the app get stuck and no error is visible.
