Hi Dennis,

I have tried running the application compiled with JDK 5 and 5 on JRE 6 and they all both produce the same result. So yes, it seems like the JRE implementation might has been changed. However, I tried searching for a reference on this issue but still could not find one yet.

Regards,

Hi Vairoj,

JVMs (at least earlier ones from Sun) did not enforce the access controls when loaded directly from the local disk. This was not a "bug", but rather a "feature" (according to Sun - see http://tinyurl.com/2losm7 for some details).

From your experience I suspect this has changed in Java 6. I haven't tried researching the details of any change - if you find out, I'd appreciate it if you'd post back here so I know.

Hi,

My application which use JibX 1.0 runs fine with JRE 1.5.0_xx. When I try running the application on JRE 6.0, the following exception is thrown:

{code}

java.lang.IllegalAccessError: tried to access method com.waveman.campaign.jibx.BindingUtils.findWarfighter(Ljava/lang/String;)Lcom/waveman/campaign/entity/Warfighter; from class com.waveman.campaign.entity.WarfighterLineItem at com.waveman.campaign.entity.WarfighterLineItem.JiBX_unit_binding_unmarshal_1_0(WarfighterLineItem.java) at com.waveman.campaign.entity.JiBX_unit_bindingWarfighterLineItem_access.unmarshal() at com.waveman.campaign.entity.JiBX_MungeAdapter.JiBX_unit_binding_unmarshal_1_0() at com.waveman.campaign.entity.Unit.JiBX_unit_binding_unmarshal_1_0(Unit.java) at com.waveman.campaign.entity.JiBX_unit_bindingUnit_access.unmarshal() at com.waveman.campaign.entity.Template.JiBX_unit_binding_unmarshal_1_0(Template.java) at com.waveman.campaign.entity.JiBX_unit_bindingTemplate_access.unmarshal() at com.waveman.campaign.entity.TemplateLibrary.JiBX_unit_binding_unmarshal_1_0(TemplateLibrary.java) at com.waveman.campaign.entity.JiBX_unit_bindingTemplateLibrary_access.unmarshal() at org.jibx.runtime.impl.UnmarshallingContext.unmarshalElement(Unknown Source) at org.jibx.runtime.impl.UnmarshallingContext.unmarshalDocument(Unknown Source) at com.waveman.campaign.jibx.JibxXmlConverter.convertXmlToLibrary(JibxXmlConverter.java:108) at com.waveman.campaign.manager.LibraryManager.openLibrary(LibraryManager.java:144) at com.waveman.campaign.ui.LibraryDocumentModel$OpenLibraryAction.actionPerformed(LibraryDocumentModel.java:240)

{code}

The method BindingUtils.findWarfighter is my custom deserializer. When I look into the problem, this exception makes sense because findWarfighter has package-level visibility and it is on a different package to WarfighterLineItem. Therefore, this method's visibility-level should be changed to public (I don't recall the reason I make them package-private). However, what I'm curious is that why it does work when running with JRE 5.0?

Cheers,
Vairoj
