Versions

• D8 version: D8 3.3.20-dev+aosp5 (build 2714f272b6761c13e00701b4a7cadf6f0e99d153 from go/r8bot (luci-r8-custom-ci-xenial-37-aihh))
• art version: ART version 2.1.0 x86_64
• java version: 17.0.10

Description

We compiled the testcase using d8 and executed it with art, discovering that the output results of the testcase were inconsistent with those obtained when using jdk17. This error does not occur every time ART is executed; it triggers approximately once every ten executions.

Step to Reproduce

1. javac -source 8 -target 8 -cp . Test.java
2. jar cvf classes.jar -C ./ *.class -C
3. java -cp d8.jar com.android.tools.r8.D8 --output ./ ./classes.jar
4. env ANDROID_LOG_TAGS=*:f ANDROID_DATA=./ /path/to/art --64 --no-compile -cp ./classes.dex Test > result_1
