Does the /Library/Java/JavaVirtualMachines/dcevm-11.0.1.6/Contents/Home/lib/hotswap/hotswap-agent.jar exist?

[ming871]

Yes

devdeiMac-Pro:bin dev$ ls -la /Library/Java/JavaVirtualMachines/dcevm-11.0.1.6/Contents/Home/lib/hotswap/hotswap-agent.jar -rw-r--r--@ 1 dev staff 1591365 12 7 00:45 /Library/Java/JavaVirtualMachines/dcevm-11.0.1.6/Contents/Home/lib/hotswap/hotswap-agent.jar

I've tested java -jar xyz.jar and it is working for me on linux. So it is failing on OSX? What about removing hotswap-agent.jar from lib/hotswap ?

[ming871]

sorry, my mistake. I mean the "jar" command to create ".jar" archive file, like "jar cvf file.jar -C fatjar/ .", not "java -jar" to run a java app from/in one jar file.

OK, you are using jdk11-dcevm as a system JDK? I do not recommend it, since it has limitations like default Serial GC (despite you can use CMS). It is intended as an alternative JDK for debugging and development. However I will try to check and fix the problem ...

[ming871]

Yeah, I add it to system PATH, I guess It's also not recommended for production environments, right? thank you very much.

[skybber]

Its not recommended, but if you can, you can try it with -XX:+UseConcMarkSweepGC - it should work quite OK, but not fully tested yet.

[ming871]

Ok, Thank you! I will try it.
