TestLinkageErrorInGenerateOopMap times out

The following test is failing the JDK14 CI:

compiler/linkage/TestLinkageErrorInGenerateOopMap.java

Here's a snippet of the log file:

#section:driver
----------messages:(9/386)----------

which doesn't help a whole lot.

Here's some snippets from the hs_err_pid file:

According to test/hotspot/jtreg/compiler/linkage/OSRWithBadOperandStack.jasm:

    public static Method test:"()V" stack 2 locals 1 {
        iconst_0;
        istore_0;
        Loop: stack_frame_type append;
        locals_map int;
        iload_0;
        // This should fail with "java.lang.VerifyError: Bad type on operand stack Exception"
        // because m1 returns an integer and m2 takes an Object.
        invokestatic Method compiler/linkage/OSRWithBadOperandStack."m1":"()I";
        invokestatic Method compiler/linkage/OSRWithBadOperandStack."m2":"(Ljava/lang/Object;)V";
        iinc 0, 1;
        ldc 100000;
        if_icmple Loop;
        return;
    }

we are expecting a VerifyError exception to be thrown. Not a crash.
