#490 Unexpected error while evaluating instruction

[nickrahn]

I'm trying out the latest 4.11beta8 and get an error on code that worked correctly with 4.9. Here's the error:

 [proguard] Unexpected error while evaluating instruction:
 [proguard]   Class       = [com/mypackage/MyController$3]
 [proguard]   Method      = [<clinit>()V]
 [proguard]   Instruction = [70] isub
 [proguard]   Exception   = [java.lang.IllegalArgumentException] (Value is not an integer value [proguard.evaluation.value.TypedReferenceValue])
 [proguard] Unexpected error while performing partial evaluation:
 [proguard]   Class       = [com/mypackage/MyController$3]
 [proguard]   Method      = [<clinit>()V]
 [proguard]   Exception   = [java.lang.IllegalArgumentException] (Value is not an integer value [proguard.evaluation.value.TypedReferenceValue])
 [proguard] Error: Value is not an integer value [proguard.evaluation.value.TypedReferenceValue]
</clinit></clinit>

Here's part of the config file I'm using:

-target 1.6
-optimizationpasses 3
-overloadaggressively
-repackageclasses 'mypkg'
-allowaccessmodification
-adaptresourcefilecontents **/logback*.xml
-adaptresourcefilenames **.*_properties,**.xml,**.xsd,**.xsql

-dontskipnonpubliclibraryclasses
-dontskipnonpubliclibraryclassmembers
-ignorewarnings

-renamesourcefileattribute SourceFile
-keepattributes SourceFile,LineNumberTable
-keepattributes Signature

There's more to the config, lots of -keep, -keepclassmembers and the default -assumenosideeffects, but I didn't include it here. Let me know if you need it or if I can provide more information.

Thanks,
Nick

Thanks for the report. This bug should be fixed for the final ProGuard 4.11, which is planned for release later this week. Until then, you can work around it with

 -optimizations !class/unboxing/enum

Sorry, but I'm still seeing this error with the released 4.11 version:

 [proguard] Unexpected error while evaluating instruction:
 [proguard]   Class       = [com/MyController$3]
 [proguard]   Method      = [<clinit>()V]
 [proguard]   Instruction = [70] isub
 [proguard]   Exception   = [java.lang.IllegalArgumentException] (Value is not an integer value [proguard.evaluation.value.TypedReferenceValue])
 [proguard] Unexpected error while performing partial evaluation:
 [proguard]   Class       = [com/MyController$3]
 [proguard]   Method      = [<clinit>()V]
 [proguard]   Exception   = [java.lang.IllegalArgumentException] (Value is not an integer value [proguard.evaluation.value.TypedReferenceValue])
 [proguard] Error: Value is not an integer value [proguard.evaluation.value.TypedReferenceValue]
</clinit></clinit>

Is this the same issue or is it something else?

Could you attach or mail me a small project that allows me to reproduce the problem?
