j2objc转换为Objective C时出错

Question

我需要将Android源转换为Objective C

但它显示错误：

java -Xbootclasspath:$J2OBJC_HOME/lib/jre_emul.jar -jar $J2OBJC_HOME/lib/j2objc.jar j2objcc

Invalid layout of java.lang.String at value

#

# A fatal error has been detected by the Java Runtime Environment:

#

#  Internal Error (javaClasses.cpp:127), pid=575, tid=4867

#  fatal error: Invalid layout of preloaded class

# JRE version:  (8.0_51-b16) (build )

# Java VM: Java HotSpot(TM) 64-Bit Server VM (25.51-b03 mixed mode bsd-amd64 compressed oops)

# Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again

Abort trap: 6

任何设置（JDK 8，Maven，SDK，Android Studio，Gradle，J2OBJC，......）

如何解决？

Answer 1

“j2objcc”不是Java源文件。如果在没有它的情况下运行命令，将显示j2objc的有效用法和标志。
