In internal testing, we see an infrequent intermittent assert because we attempt to allocate Java objects while holding a mutex:

https://github.com/openjdk/jdk/blob/e172e6a4e37cf06afee662625a01193f5528a2b1/src/hotspot/share/cds/lambdaFormInvokers.cpp#L134

    MutexLocker ml(Thread::current(), LambdaFormInvokers_lock);
    list_lines = oopFactory::new_objArray_handle(vmClasses::String_klass(), len, CHECK);
    for (int i = 0; i < len; i++) {
      Handle h_line = java_lang_String::create_from_str(_lambdaform_lines->at(i), CHECK);
