While fixing 7073631, it was noticed some positions are not being reported
correctly:

test/tools/javac/TryWithResources/DuplicateResourceDecl.java:12: warning: [try] auto-closeable resource MyResource has a member method close() that could throw InterruptedException
        try(MyResource c = new MyResource();MyResource c = new MyResource()) {
                       ^
The diagnostics says MyResource but the caret points to "c".

Similarly, it is inconsistent whether "auto-closeable resource" names a class
MyResource or an instance r1.

test/tools/javac/TryWithResources/DuplicateResourceDecl.java:12: error: c is already defined in main(String[])
        try(MyResource c = new MyResource();MyResource c = new MyResource()) {
                                                       ^
test/tools/javac/TryWithResources/DuplicateResourceDecl.java:12: warning: [try] auto-closeable resource MyResource has a member method close() that could throw InterruptedException
        try(MyResource c = new MyResource();MyResource c = new MyResource()) {
                                                       ^
test/tools/javac/TryWithResources/DuplicateResourceDecl.java:17: warning: [try] auto-closeable resource MyResource has a member method close() that could throw InterruptedException
    static class MyResource implements AutoCloseable {
           ^
test/tools/javac/TryWithResources/TwrFlow.java:14: error: exception IOException is never thrown in body of corresponding try statement
        } catch (IOException ioe) { // Not reachable
          ^

>>>>>>>>> message says IOException but caret points to "catch"
