kandi X-RAY | byte-buddy Summary
. runtime code generation for the java virtual machine. [maven central] byte buddy is a code generation and manipulation library for creating and modifying java classes during the runtime of a java application and without the help of a compiler. other than the code generation utilities that [ship with the java class library] byte buddy allows the creation of arbitrary classes and is not limited to implementing interfaces for the creation of runtime proxies. furthermore, byte buddy offers a convenient api for changing classes either manually, using a java agent or during a build. in order to use byte buddy, one does not require an understanding of java byte code or the [class file format] in contrast, byte buddy’s api aims for code that is concise and easy to understand for everybody. nevertheless, byte buddy remains fully customizable down to the possibility of defining custom byte code. furthermore, the api was designed to be as non-intrusive as possible and as a result, byte buddy does not leave any trace in the classes that were created by it. for this reason, the generated classes can exist without requiring byte buddy on the class

QUESTION
Spock is being used to execute an integration test in a Spring Boot project (2.1.18.RELEASE). When I run with 1.3-groovy-2.5, I get this error:
...ANSWER
Answered 2022-Mar-28 at 21:40Regarding java.util.ServiceConfigurationError: org.junit.platform.engine.TestEngine: org.spockframework.runtime.SpockEngine Unable to get public no-arg constructor
Spring Boot 2.1.18.RELEASE
is really old, it manages JUnit 5 to 5.3.2
while Spock 2.x requires >= 5.8
. You can try setting 5.8.1
if you can't upgrade Spring Boot to a more recent version.
As for the type reflection error, we can't say much since you didn't share any code. Only that com.foo.controller.ConversionsController.createConversionJob(ConversionsController.java:68)
probably has some weird generics or is calling something that does.
QUESTION
I have a bunch of Spring Boot 2.5.6 applications that use Mockito for unit testing. The version of Mockito that is used is the one that comes shipped within SB itself (3.9.0). The JDK is OpenJDK 11.0.12+0. Everything was working fine up until yesterday, this morning I suddenly cannot run any Mockito-based tests, all of them fail with the following:
...ANSWER
Answered 2022-Mar-30 at 09:14Not sure how much of an answer this will be, but the issue is now (seemingly) self-fixed... I'll describe what I've done and what happened in case it helps other users experiencing similar issues.
After unsuccessfully trying all the things described in the question, I had to restart the laptop (again) for an unrelated problem (Zoom wouldn't start up). Upon restart the laptop simply crashed and restarted again on its own. Then it did the same a second time. Upon the third automatic restart, I was no longer experiencing issues building my Java applications.
My guess is that the NVRAM got somehow corrupted and this was affecting the JVM's ability to accept incoming requests for attachment. On a MBP M1 one cannot reset the NVRAM as with Intel models (pressing Cmd + Opt + R + P), instead the NVRAM is supposed to self-heal when it detects something wrong. I suppose after crashing the MBP finally decided to repair the NVRAM and that's why the build starting working again.
UPDATE: I have now encountered this issue a few more times and every time the "solution" was to restart the laptop a few times until it crashed. After that the issue would disappear. This adds weight to the idea that there is some inherent instability with the combination of hardware and software specified in the question. I'll leave this as an "answered" question in case anybody else has the same issue.
UPDATE 2: This may be pure coincidence, but the issue seems to be exacerbated by the usage of an additional screen, particularly using an iPad via Sidecar.

QUESTION
I am working with Java generics and I am trying to avoid Reflection as much as possible. For that, I found that byte-buddy could help me. However, I am wondering whether I can create a class (subclass of an abstract class) using ByteBuddy that allows me to reach out to a specific attribute of a parameterized type without reflection. Such an abstract class would look like this:
...ANSWER
Answered 2022-Feb-02 at 19:22You can create such a class. Have a look at the DSL and FieldAccessor
for creating (overriding) methods that access fields.
On the other hand, it seems to me that you should rather look at MethodHandle
s which can access field values as fast as any Java byte code once generated. And I argue that resolving a method handle takes less resources then creating a class.

...ANSWER
Answered 2021-Dec-20 at 13:30It was an Intelli-J issue!
So, cleaning the Intelli-J dependency spaghetti up solved it!
- File > Invalidate cache ... and restart. Helped a bit.
- Closing the Intelli-J project. Then removed manually the ".idea" folder and any *.iml file.
Yes, I did option 1 previously. Especially doing action 2 solved it within a minute.

public class CurrencyExchange_Logic implements LogicInterface {
private final Currency_Interface currency_interface;
private final Rates_Interface rates_interface;
private final OldRates_Interface Oldrates_interface;
String start, end;
// methods
}
...ANSWER
Answered 2021-Nov-29 at 01:01Your CurrencyExchange_Logic
class has two constructors: the required args constructor, which has parameters corresponding to the 3 final
fields, and the all args constructor, with parameters corresponding to those 3 fields as well as start
and end
.
When you only have one constructor defined, Spring knows how to implicitly choose it for injection. However, when you have more than one, you have to tell it which one you want it to use, using the @Autowired
or @Inject
annotation.
I would guess you want Spring to use the required args constructor, as I doubt Spring has any way of knowing how to resolve the start
or end
fields. This can be done in lombok (@RequiredArgsConstructor(onConstructor_ = @Autowired)
), or by just explicitly writing the constructor yourself and annotating it. Note you could also get rid of the all args constructor, if you don't need it, and Spring's implicit constructor injection should "just work."
