To reproduce:

Create any bundle using the following properties:

Map<String, String> userJvmOptions = new HashMap<String, String>();
userJvmOptions.put("-Xmx", "1024m");
userJvmOptions .put("-Xms", "1024m");
params.put(USER_JVM_OPTIONS.getID(), userJvmOptions);

The bundled application won't start.

E.g. on Windows using EXE bundler I got the following values in the .cfg file:

jvmuserarg.1.name=-Xmx
jvmuserarg.1.value=1024m
jvmuserarg.2.name=-Xms
jvmuserarg.2.value=1024m

When I run the app I got:

Error occurred during initialization of VM
Initial heap size set to a larger value than the maximum heap size.


If I don't specify the Xmx value then the following code
{{
  RuntimeMXBean bean = ManagementFactory.getRuntimeMXBean();
  List<String> aList = bean.getInputArguments();

  for (String prop : aList) {
    System.out.println(prop);
  }
}}

returns:
-Xmx100m
