           Summary: LocalVariableTypeTable seems not to be updated like
                    LocalVariableTable
           Product: BCEL
           Version: 5.1
          Platform: PC
        OS/Version: Windows 2000
            Status: NEW
          Keywords: JDK1.5
          Severity: major
          Priority: P2
         Component: Main
        AssignedTo: [email protected]
        ReportedBy: [email protected]


Scenario:
I insert into a method which has a parameterized argument some instructions and
two local variables.
The methods signature looks like this:
public void doSomething( double d, ArrayList<Integer> list )
The method is situated in the class MyClassFile.

Result:
Loading the class MyClassFile which contains the new method 'doSomething'
results in a ClassFormatError:
LVTT entry for 'list' in class file MyClassFile does not match any LVT entry

This error is not produced if the method declaration is done without generics:
public void doSomething( double d, ArrayList list )

The difference is the LocalVariableTypeTable. It is not present if I do not use
generics. 
Due to the insertion of the new instructions the start_pc and the length of the
local variable have to be updated in the LocalVariableTable, which is done. 
But the corresponding entry in the LocalVariableTypeTable gets not updated its
start_pc and length entries.

LocalVariableTable ( BEFORE INSERTION ):
start_pc, length, index, name
0, 26, 0, this
0, 26, 1, d
0, 26, 3, list
LocalVariableTypeTable( BEFORE INSERTION ):
0, 26, 3, list

LocalVariableTable ( AFTER INSERTION ):
start_pc, length, index, name
44, 33, 0, this
44, 33, 1, d
44, 33, 3, list
1, 85, 4, wrapper_argumentlist
26, 60, 5, wrapper
LocalVariableTypeTable( AFTER INSERTION ):
0, 26, 3, list

The class works fine before the insertion.
I've done bcel CVS checkout, but it did not help.
The original instructions of the methods are not modified.
I simply install a wrapper around the original body. 
I add an exception handler, therefore there is also an additional entry in
the exceptiontable.
I can toggle the error behaviour by using or not using the generic argument.
generic -> error 
no generic -> no error
I tried JDK 5.0 build 1.5.0-b64 and eclipse 3.1.0 build 200412162000 as a compiler.
I use the JVR of the above mentioned JDK.
