Nothing in `isValid()` guarantees the initialization of `JavaCL`.\r\n\r\nCan be reproduced by:\r\n```\r\npublic class IsValidTest {\r\n\tpublic static void main(String[] args) {\r\n\t\tOpenCLProbeLibrary.isValid(); // Returns false\r\n\t}\r\n}\r\n```\r\n```\r\npublic class IsValidTest {\r\n\tpublic static void main(String[] args) {\r\n\t\tnew JavaCL(); // Force the static initialization of JavaCL\r\n\t\tOpenCLProbeLibrary.isValid(); // Returns true\r\n\t}\r\n}\r\n```","author":{"url":"https://github.com/jxb532","@type":"Person","name":"jxb532"},"datePublished":"2019-04-12T14:17:02.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/40/JavaCL/issues/40"}
