Description
ADDITIONAL SYSTEM INFORMATION :
OS: MacOS Sierra 10.12.6 (16G1618)
-------------------------
Java:
openjdk version "12-ea" 2019-03-19
OpenJDK Runtime Environment (build 12-ea+17)
OpenJDK 64-Bit Server VM (build 12-ea+17, mixed mode, sharing)
A DESCRIPTION OF THE PROBLEM :
With the https://bugs.openjdk.java.net/browse/JDK-8210931 libjli has moved from "jli" subdirectory into standard lib directory.
However `GetJREPath` method in `src/java.base/macosx/native/libjli/java_md_macosx.m` still assumes that `libjli.dylib` should be on `lib/jli/libjli.dylib` path.
The fix is simplly to remove `/jli` from the lastPathComponent like patch below shows:

return JNI_FALSE;
}
- const char lastPathComponent[] = "/lib/jli/libjli.dylib";
+ const char lastPathComponent[] = "/lib/libjli.dylib";
size_t sizeOfLastPathComponent = sizeof(lastPathComponent) - 1;
if (pathLen < sizeOfLastPathComponent) {
return JNI_FALSE;
REGRESSION : Last worked in version 11.0.1
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run application which uses `JNI_CreateJavaVM` to create a JVM (like Eclipse 4.9/4.10 does).
Download Eclipse application, run Eclipse with `-vm` parameter pointing to the openJDK 12 build as shown below:
$ ~/Workspace/test/Eclipse.app/Contents/MacOS/eclipse -vm ~/Workspace/test/jdk-12.jdk/Contents/Home/bin/java
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Eclipse application starts.
ACTUAL -
Eclipse fails to start with "Failed to create the Java Virtual Machine." error dialog. In console "Failed to GetJREPath()" is printed:
$ ~/Workspace/test/Eclipse.app/Contents/MacOS/eclipse -vm ~/Workspace/test/jdk-12.jdk/Contents/Home/bin/java
CONSOLE OUT:
Error: could not find libjava.dylib
Failed to GetJREPath()
FREQUENCY : always
