Hazırda bekletme, aralarında bir hata olsa bile varlığımı otomatik olarak güncelliyor

"Program" adında bir varlığım var. Bu varlıkla bir operasyon yapıyorum. Ama nasıl ve neden bilmiyorum, varlığım güncelleniyor, hatta istisna alıyorum. Yani herkes bu sorunu çözmek için bana yardımcı olabilir.

Denetleyici

@GetMapping("/testtransaction/{tid}")
public ApiResponse testTransaction(@PathVariable("tid") String tid){
     return gsService.testTransaction(tid);
}

Hizmet

@Transactional(propagation = Propagation.REQUIRED, readOnly = false, rollbackFor = Exception.class)
public ApiResponse testTransaction(String tid) {
    ApiResponse apiResponse = new ApiResponse();
    try {
        Optional<Program> existProgram = programRepository.findById(tid);
        if(existProgram.isPresent()) {
            //For testing I am setting random value
            existProgram.get().setProgramName("tid_"+(Math.floor(Math.random() * 90 + 10)));
                
            try {
                int err = 8/0;
            }catch(Exception e) {
                throw new EntityNotFoundException(Program.class, "prog cd", tid);
            }
                    
            programRepository.save(existProgram.get());
            apiResponse.setData("Success");
        }else {
            apiResponse.setError("Program details not found for "+tid);
            apiResponse.setStatusCode(500);
        }
    }catch(Exception e) {
        apiResponse.setError("Something went wrong while testing.");
        apiResponse.setStatusCode(500);
        return apiResponse;
    }
    return apiResponse;
}
