pre 3.5M4 - Build id: I20081211-0100 VM is Sun 1.6.0_12-ea When debugging the following program, in presence of a StackOverflowError, the debugger becomes non responsive. Steps: 1. In following program, place a breakpoint on line 3 public class X { public static void main(String[] args) { new X().foo(1, 2, true); // BREAKPOINT on this line } void foo(int i, int j, boolean b) { if (b) { foo( i, j, bar( i < j)); } else { boolean b1 = bar( b); } } boolean bar(boolean b) { return b; } } 2. Run as Java app; once hitting the breakpoint, step into #foo(...) using F5 3. When reaching recursive call to #foo(...) press F6 (step over) 4. Stackoverflow is occurring (expected) 5. Observe debugger is hanging

Steps can be simplified into: 1. In following program, place a breakpoint on line 3 public class X { public static void main(String[] args) { new X().foo(1, 2, true); // BREAKPOINT on this line } void foo(int i, int j, boolean b) { if (b) { foo( i, j, bar( i < j)); } else { boolean b1 = bar( b); } } boolean bar(boolean b) { return b; } } 2. Run as Java app; once hitting the breakpoint, step over (F6) 3. Stackoverflow is occurring (expected) 4. Observe debugger is hanging
Only way out I could find is to kill Eclipse
Debugging stack overflows has been problematic since day 1 - see bug 19217. However, perhaps we could recognize the exception and avoid retrieving so many stack frames.
Anything avoiding me to kill my instance of Eclipse would be good.
Feels to me this should be investigated. A solution where you do not expand more than a certain amount of stack frames would make sense...
