Netbeans调试器在Class.java.getDeclaredConstructors处停止

Question

I'm trying to debug web application in netbeans 7.2.1 with glassfish server 3.1. Debugging worked fine previously.

But Netbeans debugger suddenly started to print this message:

Thread admin-thread-pool-4848(2) stopped at Class.java.getDeclaredConstructors0.

Debugger stops at that line as if there was a breakpoint there and also at this line:

 res = Reflection.filterFields(this, getDeclaredFields0(publicOnly));
 in method private Field[] privateGetDeclaredFields(boolean publicOnly)

If I press a button to continue it stops again at same point for several times and deploying continues for a long time until it fails with message

Deployment error: Deployment timeout has exceeded.

I know it's not much information, but maybe someone has a hint what it could be related to?

Answer 1

I had the exact same problem using Netbeans8, Glasshfish 4.0 and JavaEE JAX-RS. The problem was a breakpoint placed inside a lib that was part of a previous project I was working on.

Solved it by clearing/deleting all breakpoints. To do so, on the Netbeans top bar: window -> debugging -> breakpoints -> and then disable them or right click and delete all of them.
