            You are running the project via Java 1.8 and add the --add-opens option to the runner. However Java 1.8 does not support it.

            So, the first option is to use Java 11 to run the project, as Java 11 can recognize this VM option.

            Another solution is to find a place where --add-opens is added and remove it. Check Run configuration in IntelliJ IDEA (VM options field) and Maven/Gradle configuration files for argLine (Maven) and jvmArgs (Gradle)

            Asked 2022-Mar-17 at 13:46

            I've created a new Java project in IntelliJ with Gradle that uses Java 17. When running my app it has the error Cause: error: invalid source release: 17.

            My Settings

            I've installed openjdk-17 through IntelliJ and set it as my Project SDK.

            The Project language level has been set to 17 - Sealed types, always-strict floating-point semantics.

            In Modules -> Sources I've set the Language level to Project default (17 - Sealed types, always strict floating-point semantics).

            In Modules -> Dependencies I've set the Module SDK to Project SDK openjdk-17.

            In Settings -> Build, Execution, Deployment -> Compiler -> Java Compiler I've set the Project bytecode version to 17.

            The message typically entails that your JAVA_HOME environment variable points to a different Java version.

            Here are the steps to follow:

            • Close IntelliJ IDEA
            • Open a terminal window and check your JAVA_HOME variable value:
              • *nix system: echo $JAVA_HOME
              • Windows system: echo %JAVA_HOME%
            • The JAVA_HOME path should be pointing to a different path, then set it to the openjdk-17 path:
              • *nix system: export JAVA_HOME=/path/to/openjdk-17
              • Windows system: set JAVA_HOME=path\to\openjdk-17
            • Open your project again in IntelliJ IDEA
            • Make sure to set both source and target compatibility versions (not only the sourceCompatibility)

            You should be able to build your project.

            EDIT: Gradle Toolchain

            You may need also to instruct Gradle to use a different JVM than the one it uses itself by setting the Java plugin toolchain to your target version:

            I am trying to compile and load dynamically generated Java code during runtime. Since both ClassLoader::defineClass and Unsafe::defineAnonymousClass have serious drawbacks in this scenario, I tried using hidden classes via Lookup::defineHiddenClass instead. This works fine for all classes that I tried to load, except for those that call lambda expressions or contain anonymous classes.

            You can not turn arbitrary classes into hidden classes.

            The documentation of defineHiddenClass contains the sentence

            • On any attempt to resolve the entry in the run-time constant pool indicated by this_class, the symbolic reference is considered to be resolved to C and resolution always succeeds immediately.

            What it doesn’t spell out explicitly is that this is the only place where a type resolution ever ends up at the hidden class.

            But it has been said unambiguously in bug report JDK-8222730:

            For a hidden class, its specified hidden name should only be accessible through the hidden class's 'this_class' constant pool entry.

            The class should not be accessible by specifying its original name in, for example, a method or field signature even within the hidden class.

            How to configure proxy in emulators in new versions of Android Studio?

            JMH using java 17, no dead code elimination
            Asked 2022-Feb-09 at 17:17

            I run sample JHM benchmark which suppose to show dead code elimination. Code is rewritten for conciseness from jhm github sample.

            Those samples depend on JDK internals.

            Looks like since JDK 9 and JDK-8152907, Math.log is no longer intrinsified into C2 intermediate representation. Instead, a direct call to a quick LIBM-backed stub is made. This is usually faster for the code that actually uses the result. Notice how measureCorrect is faster in JDK 17 output in your case.

            But for JMH samples, it limits the the compiler optimizations around the Math.log, and dead code / folding samples do not work properly. The fix it to make samples that do not rely on JDK internals without a good reason, and instead use a custom written payload.

            This is being done in JMH here:

            Java doesn't mind if you install multiple versions. This is often required; java is not backwards compatible (it tries to change little, but e.g. the java8 to java9 transition broke a ton of stuff, much of it needless and much of it not reasonably expectable or fixable by libraries and apps, so a bunch of java apps and libraries only run on java8 - just an example).

            So, yes, you have installed JDK17. Also, yes, if you just run java without specifying which one you want, you so happen to get java13 here.
