[DERBY-4458] Dalvik / Andoid compatibility

• Type: Improvement
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: 10.5.3.0
• Component/s: Miscellaneous
• Environment: dx 1.2 (from the Android SDK 2.0) running on Java 1.6
• Assignee: Unassigned
• Reporter: Thomas Görres

Description

derby.jar cannot be used on mobile devices running the Android OS. Android uses Dalvik as runtime environment, and the classfiles from derby.jar cannot be translated to Dalvik byte code.

Steps to repeat:
1. get the Android SDK from http://developer.android.com
2. navigate to [android-sdk]/platforms/android-1.5/tools
3. execute ./dx --dex path/to/derby.jar

The dx tool should convert the JRE byte code to Dalvik byte code. Instead, it spits out this warning several time:
warning: Ignoring InnerClasses attribute for an anonymous inner class that doesn't come with an associated EnclosingMethod attribute. (This class was probably produced by a broken compiler.)

Then it runs out of memory:
