应用错误收集

我正在开展一个项目，我正在尝试检查一些验证，但我发现产品有＆＃39; product_id＆＃39;提交到Exception thrown: Exception in thread "main" java.lang.OutOfMemoryError: Java heap space at java.util.LinkedHashMap.newNode(LinkedHashMap.java:256) at java.util.HashMap.putVal(HashMap.java:630) at java.util.HashMap.put(HashMap.java:611) at sun.util.resources.OpenListResourceBundle.loadLookup(OpenListResourceBundle.java:146) at sun.util.resources.OpenListResourceBundle.loadLookupTablesIfNecessary(OpenListResourceBundle.java:128) at sun.util.resources.OpenListResourceBundle.handleKeySet(OpenListResourceBundle.java:96) at java.util.ResourceBundle.containsKey(ResourceBundle.java:1807) at sun.util.locale.provider.LocaleResources.getTimeZoneNames(LocaleResources.java:262) at sun.util.locale.provider.TimeZoneNameProviderImpl.getDisplayNameArray(TimeZoneNameProviderImpl.java:122) at sun.util.locale.provider.TimeZoneNameProviderImpl.getDisplayName(TimeZoneNameProviderImpl.java:98) at sun.util.locale.provider.TimeZoneNameUtility$TimeZoneNameGetter.getName(TimeZoneNameUtility.java:325) at sun.util.locale.provider.TimeZoneNameUtility$TimeZoneNameGetter.getObject(TimeZoneNameUtility.java:281) at sun.util.locale.provider.TimeZoneNameUtility$TimeZoneNameGetter.getObject(TimeZoneNameUtility.java:267) at sun.util.locale.provider.LocaleServiceProviderPool.getLocalizedObjectImpl(LocaleServiceProviderPool.java:281) at sun.util.locale.provider.LocaleServiceProviderPool.getLocalizedObject(LocaleServiceProviderPool.java:265) at sun.util.locale.provider.TimeZoneNameUtility.retrieveDisplayName(TimeZoneNameUtility.java:135) at java.util.TimeZone.getDisplayName(TimeZone.java:400) at java.util.Date.toString(Date.java:1045) at java.lang.String.valueOf(String.java:2982) at java.lang.StringBuilder.append(StringBuilder.java:131) at com.test.perf.testpgm.main(testpgm.java:112)脚本后，参数未被正确清理，该脚本可能会泄露软件的安装路径，从而导致机密性丢失。

所以在检查产品的product_id的格式之后，它只能用数字表示，但是格式可能是字母数字，如果是，那么行为究竟是什么。

Opencart中产品的Product_ID可以是字母数字吗？
