I have problem with loading Java VM. When I do LoadVM program gives access violation. On other computer it works fine. Here is some code that works but not on my machine:

uses jni;
var

Options: array [0..1] of JavaVMOption;
VM_args: JavaVMInitArgs;
ErrCode: Integer;
AJavaVM: TJavaVM;
AJavaEnvMain: TJNIEnv;
JrePath, ProgramPath, LibPath, File1, File2: string;

begin

  ProgramPath := 'd:\testjava\exe\';
  JrePath := ProgramPath + 'JRE\bin\client\';
  LibPath := ProgramPath + 'JRE\lib\ext\';   

   File1 := LibPath + 'file1.jar';
   File2 := LibPath + 'file2.jar';

  AJavaVM := TJavaVM.Create(JNI_VERSION_1_8, JrePath + 'jvm.dll');

   FillChar(Options, SizeOf(Options), #0);

   Options[0].optionString := PAnsiChar(AnsiString('-D java.class.path=' + File1 + ';' + File2));

   VM_args.version := JNI_VERSION_1_8;
   VM_args.Options := @Options;
   VM_args.nOptions := 1;
   ErrCode := AJavaVM.LoadVM(VM_args); **//access violation**

   if ErrCode < 0 then
   raise Exception.CreateFmt('Initialization error JVM, błąd %d.', [ErrCode]);

  • When you see the AV, are you running inside the debugger? Does the AV actually reach your code? If not, then don't worry about it. Commented Oct 31, 2022 at 19:57
  • I'm running inside the debugger. That AV causes not working Java VM. So I can't go further. Commented Nov 4, 2022 at 9:46
