Class Javalaunchhelper Is Implemented in Both ... Libinstrument.Dylib. One of the Two Will Be Used. Which One Is Undefined

Class JavaLaunchHelper is implemented in two places

You can find all the details here:

• IDEA-170117 "objc: Class JavaLaunchHelper is implemented in both ..." warning in Run consoles

It's the old bug in Java on Mac that got triggered by the Java Agent being used by the IDE when starting the app. This message is harmless and is safe to ignore. Oracle developer's comment:

The message is benign, there is no negative impact from this problem
since both copies of that class are identical (compiled from the exact
same source). It is purely a cosmetic issue.

The problem is fixed in Java 9 and in Java 8 update 152.

If it annoys you or affects your apps in any way (it shouldn't), the workaround for IntelliJ IDEA is to disable idea_rt launcher agent by adding idea.no.launcher=true into idea.properties (Help | Edit Custom Properties...). The workaround will take effect on the next restart of the IDE.

I don't recommend disabling IntelliJ IDEA launcher agent, though. It's used for such features as graceful shutdown (Exit button), thread dumps, workarounds a problem with too long command line exceeding OS limits, etc. Losing these features just for the sake of hiding the harmless message is probably not worth it, but it's up to you.

Xtend - saved files contain repeated data

you store the file content for some reason as a member in the generator and never reset it

val root = resource?.allContents?.head as ProblemSpecification;
s += readFile(path_sigAlloyDeclaration+"sigAlloyDeclaration.txt")

i assume s either should be local to the doGenerate method or be reset at the start

s = ""
val root = resource?.allContents?.head as ProblemSpecification;
s += readFile(path_sigAlloyDeclaration+"sigAlloyDeclaration.txt")

How to enter fullscreen mode on launch

If anyone is interested in the solution I managed to find a solution to my issue. Here is the code:

     WindowGroup {
         ContentView()
             .onAppear {
                 DispatchQueue.main.async {
                     if let window = NSApplication.shared.windows.last {
                         window.toggleFullScreen(nil)
                     }
                 }
             }
        }

asyncprofiler malloc undefined category

Container environment is not related here.

It seems like libc (where malloc implementation resides) on your system is compiled without frame pointers. So the standard stack walking mechanism in the kernel is unable to find a parent of malloc frame.

I've recently implemented an alternative stack walking algorithm that relies on DWARF unwinding information. New version has not been yet released, but you may try to build it from sources. Or, for your convenience, I prepared the new build here: async-profiler-2.6-dwarf-linux-x64.tar.gz

Then add --cstack dwarf option, and all malloc stack traces should be in place.
