Arch Linux

A DESCRIPTION OF THE PROBLEM :
The JDK8 doesn't contain enough debug information, the LocalVariableTables are not generated. This means that the Eclipse debugger can't show any variable names. As an example, this is the bytecdoe of java.util.ArrayList#subList:

public java.util.List<E> subList(int, int);
descriptor: (II)Ljava/util/List;
flags: ACC_PUBLIC
Code:
stack=7, locals=3, args_size=3
0: iload_1
1: iload_2
2: aload_0
3: getfield #1 // Field size:I
6: invokestatic #63 // Method subListRangeCheck:(III)V
9: new #64 // class java/util/ArrayList$SubList
12: dup
13: aload_0
14: aload_0
15: iconst_0
16: iload_1
17: iload_2
18: invokespecial #65 // Method java/util/ArrayList$SubList."<init>":(Ljava/util/ArrayList;Ljava/util/AbstractList;III)V
21: areturn
LineNumberTable:
line 996: 0
line 997: 9
Signature: #188 // (II)Ljava/util/List<TE;>;

In JDK7 the information is present. Here the bytecode looks like this:

public java.util.List<E> subList(int, int);
flags: ACC_PUBLIC
Code:
stack=7, locals=3, args_size=3
0: iload_1
1: iload_2
2: aload_0
3: getfield #2 // Field size:I
6: invokestatic #60 // Method subListRangeCheck:(III)V
9: new #61 // class java/util/ArrayList$SubList
12: dup
13: aload_0
14: aload_0
15: iconst_0
16: iload_1
17: iload_2
18: invokespecial #62 // Method java/util/ArrayList$SubList."<init>":(Ljava/util/ArrayList;Ljava/util/AbstractList;III)V
21: areturn
LineNumberTable:
line 954: 0
line 955: 9
LocalVariableTable:
Start Length Slot Name Signature
0 22 0 this Ljava/util/ArrayList;
0 22 1 fromIndex I
0 22 2 toIndex I
LocalVariableTypeTable:
Start Length Slot Name Signature
0 22 0 this Ljava/util/ArrayList<TE;>;
Signature: #214 // (II)Ljava/util/List<TE;>;

The proposed fix was to add "-g" to the JAVAC_FLAGS.
