Adding type parameter to trivial class triggers compile error in java 1.5

[HK]

First I compile this without error with javac from 1.5.0_04

public class Bla {
public static final int x = Bli.innerX;
private class Bli {
public static final int innerX = 1;
}
}

Then I add an unused type parameter:

public class Bla<T> {
public static final int x = Bli.innerX;
private class Bli {
public static final int innerX = 1;
}
}

and the compilation results in this error:

% ./jdk1.5/bin/javac -source 1.5 Bla.java
Bla.java:4: non-static class Bla.Bli cannot be referenced from a static
context
public static final int x = Bli.innerX;
^
1 error

Is this a bug or a feature?

Harald.
