Easiest example I can think of would be a method that sends some content to a JMS server. If you are in the context of a transaction, you want the message to be coupled to the transaction scope. But if there isn’t already a transaction running, why bother calling the transaction server also and starting … Read more
Jackson processes @JsonTypeInfo before choosing which Deserializer to use, probably because the choice of Deserializer could depend generally on the type. However, you can easily disable this on a per-field basis the same way you specify custom Deserializer – by annotating the field directly: @JsonDeserialize(using = DefinitionDeserializer.class) @JsonTypeInfo(use = JsonTypeInfo.Id.NONE) private Definition definition;
You’re dealing with sleep times termed in tens of seconds. The possible savings by changing your sleep option here is likely nanoseconds or microseconds. I’d prefer the latter style every time, but if you have the former and it’s going to cost you a lot to change it, “improving performance” isn’t a particularly good justification. … Read more
‘for backwards compatibility’ seems a sufficient reason for the type erasure of class generic types – it is needed e.g. to allow you to return an untyped List and pass it to some legacy code. The extension of this to generic methods seems like a tricky sub-case. The JLS snippet from 4.8 (which you quote) … Read more
tl;dr I think you are running into GC-related behavior, where threads are being put in waiting state to allow for garbage collection. I do not have the whole truth but I hope to provide some pieces of insight. First thing to realize is that the number in brackets, [0x00007fe64df9a000], is not the address of a … Read more
Short answer: there is no dedicated debug option for CDI (as no such thing is required by the spec), and no dedicated debug option for Weld. Long Answer: There is a lot you can do on your own. Familiarise yourself with the extension mechanism of CDI, and you’ll discover that you can easily (really!) write … Read more
Use File > Invalidate Caches / Restart option which should invalidate local caches. Hopefully it’s a glitch in the dialog cache.
Like you said, it fails because the arguments are different. Take a look at the test below and you’ll see that the second test method will fail because the status in your MyClass instance is different from SomeStatus that you passed in the matcher. public class MatcherTest { class MyClass{ private String status; MyClass(String status) … Read more
Just put those resources in the source/package structure and use ClassLoader#getResource() or getResourceAsStream() to obtain them as URL or InputStream from the classpath by the full qualified package path. ClassLoader classLoader = Thread.currentThread().getContextClassLoader(); InputStream input = classLoader.getResourceAsStream(“/image.gif”); // … Or if it is in the same package as the current class, you can also obtain … Read more
