Probably the same problem as #8594.

Changing the `TR_ASSERT()` to a `TR_ASSERT_FATAL_WITH_NODE()` shows the following: ``` Assertion failed at /home/ubuntu/openj9/openj9-openjdk-jdk11/omr/compiler/il/OMRBlock.cpp:280: (frequency >= 0) VMState: 0x00050fff Node 0xffff9579b720 [ificmpne]: Block frequency must be non negative compiling java/util/ServiceLoader.findStaticProviderMethod(Ljava/lang/Class;)Ljava/lang/reflect/Method;...

I tried to reproduce the assertion failure on x86 Linux ([Link](https://hyc-runtimes-jenkins.swg-devops.com/job/Pipeline_Build_Test_JDK11_x86-64_linux/5578/)), but it did not fail.

Disabling GlobalVP gives the correct result, too. ``` $ java -Xjit:limit=mainTest,optLevel=hot,disableAsyncCompilation Test 0 $ java -Xjit:limit=mainTest,optLevel=hot,disableAsyncCompilation,disableGlobalVP Test -10 ```

UMA build has been disabled recently by https://github.com/ibmruntimes/openj9-openjdk-jdk/pull/928 and other PRs. This issue is no longer needed.

Could you share the binary `build/macosx-aarch64-server-release/support/modules_libs/java.base/libjava.dylib`, please? I am going take a look into it.
