    Step 1: I installed of Eclipse (2.1.1).

    Step 2: I wrote a very small test program to try debugging features. (Program consisted of 10 System.out.println() statements paired with System.out.flush() statements in the main method of a Java class.) Debugging worked exectly as expected. (Execution stops at break point with statement highlighted, single step enabled and functions as expected, continue button enables and functions as expected.)

    Step 3: I installed MyEclipse (2.6.3).

    Step 4: I tried debugging my test program again. Execution behavior was NOT as expected. Setting a breakpoint caused execution to stop before any output was produced. Clicking the pause button followed by the continue button caused expected out to be produced. Execution did not stop where the break point was set.

    Operating system: Windows XP – Home Edition
    Eclipse: Version: 2.1.1 – Build id: 200306271545
    (Fresh install with “Examples” plugin)
    No other plugins installed.
    Plugins in the <eclipse>/plugins directory like org.eclipse.pde.* = 7
    MyEclipse version 2.6.3 installed in “C:\MyEclipse Enterprise Workbench\V2.6.3”.
    Using JDK version 1.4.0 to run Eclipse.

    I’m perplexed too. 🙂

    We have seen very odd behavior with JDK 1.4.0, because the Java debugger implementation in it was buggy. So, saying it doesn’t correctly doesn’t surprise me, but saying it did work until MyEclipse was installed is very surprising.

    Can you try an experiment? Can you download JDK 1.4.1 or 1.4.2 and try that? You don’t necessarily need to run Eclipse with it, or make it your default or anything, but try launching your test application with it, by modifying the launch configuration, to see if the behavior changes. I expect it will.

    I installed the J2SE version 1.4.2_02 SDK and debugging is now working just fine – in a simple Java application, in a servlet and in a JSP. Amazing! Thanks for the prompt help and for an excellant product.

    BTW, did I miss a release note that a SDK > 1.4.0 is required?

    Glad to hear things are working. We are updating our FAQ to make users more aware of some of the debugging issues caused by using the early JDK 1.4.x releases.
