错误NumberFormatException：对于输入字符串：“ 2.0”，启动Jdeveloper

Question

在测试管理员和SOA服务器后，我安装了BPM并关闭了VM，然后从oracle网站下载了带有Oracle 12c 12.2.1.1的新VM。

现在，当我尝试启动Jdeveloper时，出现以下错误：

我在网上搜索并找到此链接，所以我遵循并删除了该<HOME>/.jdeveloper/system12.1.3.0.41.140521.1008/system_cache文件夹以及用于12.2.1和12.2.1.1的文件夹，但未成功。任何的想法？

提前致谢！！

Answer 1

我对OTN的预构建VM遇到相同的问题。

我先清除了所有<HOME>/.jdeveloper/system12.*/system_cache文件夹：无效果。完全删除所有现有<HOME>/.jdeveloper/system12.*文件夹：也无效。我还删除了所有<HOME>/.jdeveloper/12.*文件夹，然后重新启动了JDeveloper。还是一样的错误。

但是现在创建<HOME>/.jdeveloper/12.2.1.1.0了一个product.conf文件夹：一个文件。

在此文件中，SetJavaHome已被注释掉。似乎默认的JDK是问题的根源。我将其更改为SetJavaHome /usr/java/jdk1.8.0_51。保存文件并重新启动JDeveloper，现在它将按预期启动。
