On Windows 10 does not have this issue.
Has anyone encountered the same problem before?
The Rust logs do not indicate any issue with starting JVM...
As a first question, are you sure that the dll exists in the expected path: "C:\Program Files\Java\jre-1.8\bin\sunmscapi.dll"?
In case it exists, I see that the -Djava.library.path=D:\workflow\deps is set. Have you tried adding C:\Program Files\Java\jre-1.8\bin to the java_opts once you are building the Jvm? Something like:
JvmBuilder::new()
.with_default_classloader()
.classpath_entry(ClasspathEntry::new(&config.file))
.java_opts(java_opts)
// Try adding the next two calls
.with_no_implicit_classpath()
.java_opt(JavaOpt::new(
"-Djava.library.path=D:\workflow\deps\;C:\Program Files\Java\jre-1.8\bin\",
))
.build()

This time there is an error in the creation of the JVM.
What is it? Can you check in the console?
Perhaps some new issues are interfering with this test, I will try again.
Hi: astonbitecode!
No problem solved!
Calling with_no_implicit_classpath() will affect -Djava.class.path,I directly modified the function java_library_path() for testing。
I have set the path according to the configuration of the java.exe -jar my.jar package, but the issue remains the same as before.
I think java.exe must have done something, but we don't know!
Ok used an OCR tool and saw "Error opening file. The system could not find the specified file".
Could it be a permissions issue?
