Description Igor Fedorenko 2005-06-06 09:24:38 EDT

Eclipse I20050527-1300, SUN 1.5.0_3, Win2k Sp4. Internal compiler error
Compiling the following two classes

==============================
package bugs;
public class AbsC {
	public <T> T[] resize(T[] src, T[] dest) {
		return dest;
	}
}
==============================
package bugs;
public class ConrC<T> extends AbsC {
	T[][] data;
	protected void allocateChunkSlots(int maxChunkNo) {
		data = resize(data, new Object[maxChunkNo][]);
	}
}
===============================


Relevant content of .log (looks like compiler swallows nested exceptions too)
