Google App Engine java eclipse plug-in cannot suspend on exception. Is this normal?

GAE java plugin doe开发者_如何学Pythons not suspend at any exception. So I'm seeing only stack-trace. The exception is just simple type-casting exception from bug on my code. (Not a custom breakpoint) I installed all tools with default setting and nothing configured additionally. Is this normal?

And addition, DataNeucleus enhancing and app startup to debugging is so slow too. Is this normal too?

Env:

• Mac OS X 10.6.2
• Java SE 1.6.0_17 (bundle with OS)
• Eclipse + GAE plugin for Java. (without AJAX component, downloaded yesterday)

When it comes to eclipse breapkpoints which are not respected, one possible cause is the bug Breakpoints fail to hit under JDK 1.6.0_14

So if you are using jdk6u14 or u15, you need to upgrade your JVM.
That would not explain the slow behavior of the debugging session, but at least would solve one of the issues you mention.

Did you add Java Exception Breakpoint(Run->Add Java Exception BreakPoint)?
