Bug 10690

Description Dirk Baeumer 2002-03-04 12:17:49 EST

Build 20020228

- create a new snippet in jdt.ui
- typed 1 + 1
- selected it and pressed display
- the debugger came up with the following stack

Thread [main] (Suspended)
	org.eclipse.jdt.internal.debug.ui.snippeteditor.ScrapbookMain1.eval
(java.lang.Class) line: 14
	java.lang.reflect.Method.invoke(java.lang.Object, java.lang.Object[])

I also tried to eval something in the context of the active stack frame. Here 
is the stack trace:

I selected ast.resolveWellKnownType("boolean") in the stack frame 

org.eclipse.jdt.internal.corext.dom.Bindings.createType
(org.eclipse.jdt.core.dom.ITypeBinding, org.eclipse.jdt.core.dom.AST) line: 131

and activate inspect and got the following walkback on console:

<VM waiting for proxy on port=11598>
<proxy connected from dbaeumer>

JIT: Warning debugger active -- disabling JIT.
