我正在尝试运行 Hyperledger Indy SDK 的 java 示例。我已经克隆了 indy-sdk 的 git 存储库，构建了 libindy.so 并使用了 Java Indy 库版本 1.15.0（也尝试了 1.14.2、1.16.0-rc-162，同样的问题）。我使用以下命令运行示例：
RUST_BACKTRACE=full LD_LIBRARY_PATH=/home/myself/projects/hyperledger/indy-sdk/libindy/target/debug:$LD_LIBRARY_PATH mvn exec:java -Dexec.mainClass=Main
libindy.so 确实在此目录中，请仔细检查。该命令的输出是：

当我在一些 Java (Groovy) 代码中自己尝试时也会发生同样的情况：
String stewardSeed = "000000000000000000000000Steward1"
String did_json = "{\"seed\": \"" + stewardSeed + "\"}"
CreateAndStoreMyDidResult stewardDid = createAndStoreMyDid(wallet, did_json).get()
抛出相同的恐慌错误消息。我在这里做错了什么？我可能忘记在 did_json 选项中设置的任何内容？我也尝试过提交并清空 did_json ("{}")，再次出现同样的错误。
非常感谢您的帮助！
