How exactly are you supposed to use CloseableThreadContext?

[Matt Sicker]

I tried doing it like in the javadocs and get a compilation error:

@Test
public void name() throws Exception {
try (CloseableThreadContext.put("key", "value")) {
}
}

List of errors:

RequestIdFilterTest.java:12: error: <identifier> expected
                try (CloseableThreadContext.put("key", "value")) {
                                               ^
RequestIdFilterTest.java:12: error: ')' expected
                try (CloseableThreadContext.put("key", "value")) {
                                                ^
RequestIdFilterTest.java:12: error: '{' expected
                try (CloseableThreadContext.put("key", "value")) {
                                                     ^
RequestIdFilterTest.java:12: error: not a statement
                try (CloseableThreadContext.put("key", "value")) {
                                                       ^
RequestIdFilterTest.java:12: error: ';' expected
                try (CloseableThreadContext.put("key", "value")) {
                                                              ^
RequestIdFilterTest.java:17: error: reached end of file while parsing
}
 ^

Am I doing something wrong here?
