        OpenJDK Runtime Environment (build 17.0.2+8-86)
        OpenJDK 64-Bit Server VM (build 17.0.2+8-86, mixed mode, sharing)

        openjdk version "18" 2022-03-22
        OpenJDK Runtime Environment (build 18+36-2087)

        OpenJDK 64-Bit Server VM (build 19-ea+13-808, mixed mode, sharing)

        A DESCRIPTION OF THE PROBLEM :
        When we run the test in jdk17.0.2, jdk18 and jdk19-ea, all in compiled mode(with "-Xcomp"), it crashed with the following message. But when run the test in mixed mode or interpreted mode(with "-Xint), it passed successfully.

        The error message in compiled mode:

        STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
        1. extract the bug.zip
        2. in dictionary "bug", run command:
        java -cp ./bugFiles:./util:./junit.jar:./hamcrest.jar:./target/classes:./target/test-classes org.junit.runner.JUnitCore com.alibaba.fastjson.deserializer.issue1463.TestIssue1463

        you may add "-Xcomp" or "-Xint" to get different results.

        EXPECTED VERSUS ACTUAL BEHAVIOR :
        EXPECTED -
        The result should be the same since the program are the same, no matter in compiled mode, mixed mode or interpreted mode.
        ACTUAL -
        When run in compiled mode(with "-Xcomp"), it crashed. But when run in mixed mode or interpreted mode(with -Xint), it passed successfully.

        ---------- BEGIN SOURCE ----------
        to be attached in bug.zip
        ---------- END SOURCE ----------

        CUSTOMER SUBMITTED WORKAROUND :
        run the command without -Xcomp or with -Xint

        FREQUENCY : always
