I am having the same problem since the Q-builds (before beta releases). Before Netbeans4 Beta2 (for q-builds) i had jdk-1. 4.2_05. I am using JDK 5.0 with Netbeans4.0 Beta2 Bundle now. Currently, when i opened Netbeans4, it gives me the Error-1 written at the bottom of the message. Also, after i opened a project, when trying to open a java source file in the project, it gives me Error-2 written at the bottom of the message. (Unforunately, i get the same error for all attempts for all files) I also tried to remove the .netbeans directory in the user.home: Nothing changed.

Created attachment 18440 [details] log file for netbeans
javacore or mdr problem. Re-assigning.
This looks like some IO problem, or problem with corrupted installation jars. Are you sure your disk is not full and the disk access rights are set properly?
I am sure that the disk is not full. I am using windows, so i dont think that it is an access right problem. Can you tell me the name of the files to look for corruption and permission rights?
Could you please try this with the current dev build and attach the messages.log from it to this issue (in case the bug is still there)?
Thank you very much. It seems that the problem is solved for 200410251800 daily build.
Thanks for the update.
