Thank you again, that solved that problem, and now another has arose. It can run and compile on our embedded system, but sound no longer functions and I'm now at the point where I need to ask for help again. Running the same code on Java 8 sound works with no errors, running it on the newly built 11 crashes every time. It doesn't seem to be able to recognize the mixer properly in 11 and I have not been able to figure out why and whether it's a problem with my build, or a bug, or some other configuration I've still been missing.
I've tried using client, server, and zero variants, with and without fastdebug enabled, I've also tried using two different toolchains, and even got a build on the older mercurial tree working and tried that as well. I've also tried multiple different sound files, and they all have the same error. I've also tried setting the sound.properties to: javax.sound.sampled.Clip=com.sun.media.sound.DirectAudioDeviceProvider javax.sound.sampled.Port=com.sun.media.sound.PortMixerProvider javax.sound.sampled.SourceDataLine=com.sun.media.sound.DirectAudioDeviceProvider javax.sound.sampled.TargetDataLine=com.sun.media.sound.DirectAudioDeviceProvider The only major difference I've noticed between my build of 11, and the working build of 8, is 8 also has a libjsoundalsa.so, and my 11 build does not. Here's the output of java8 version and java11 version too: # java8 -version java version "1.8.0_144" Java(TM) SE Runtime Environment (build 1.8.0_144-b01) Java HotSpot(TM) Client VM (build 25.144-b01, mixed mode) [java -version openjdk version "11.0.14-internal" 2022-01-18 OpenJDK Runtime Environment (build 11.0.14-internal+0-adhoc.johnc.jdk11u-dev) OpenJDK Client VM (build 11.0.14-internal+0-adhoc.johnc.jdk11u-dev, mixed mode) The app I've been collecting information with just gets the mixers, and any data lines and prints their values, and then plays a .wav file using SourceDataLine, and again with Clip. I use -Daudio.mixer="M1 PCM [default]" because in the Java 11 build, setting it to null for the default just returns null, and it doesn't even return the "Found Audio Mixer" line.

Default location: > /usr/lib/jvm/jdk11/server/jdk/bin/core OK, good. This indicates that ARM backend had tried to encode some instruction that is beyond ARM spec. It makes sense that release builds SIGILL when than happens: the instruction is garbage. The next step is to look into hs_err and see the call stack for that assert, which would drive you to Hotspot code. From the code inspection, that is likely to be assembler_arm.hpp:encoding2(), which is called from pld/pldw instructions... It looks suspiciously like: https://nam12.safelinks.protection.outlook.com/?url=https%3A%2F%2Fbugs.openjdk.java.net%2Fbrowse%2FJDK-8222825&data=04%7C01%7Cjohnc%40synel-americas.com%7C6679a2c2c1de4f4bd1df08d98f13b673%7Cce62291737b444dcb33e6a5ae5e16b70%7C0%7C0%7C637698137114616983%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=fj4NOYRZSrRqjaufbwF6l58j3xxjt9M8VvCuTKs%2BFjw%3D&reserved=0 ...so maybe you want to try to apply this patch and build again: https://nam12.safelinks.protection.outlook.com/?url=https%3A%2F%2Fcr.openjdk.java.net%2F~bulasevich%2F8222825%2Fwebrev.00.jdk11%2F&data=04%7C01%7Cjohnc%40synel-americas.com%7C6679a2c2c1de4f4bd1df08d98f13b673%7Cce62291737b444dcb33e6a5ae5e16b70%7C0%7C0%7C637698137114616983%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=ilicvIKCCyC2tEhQsr4yrxtWjuKH6pU%2FDv1QaI3e30I%3D&reserved=0 -- Thanks, -Aleksey The information contained in this message may be privileged, confidential, and protected from disclosure.
