I had NetBeans up for a few days and then one day I tried to compile and it gave me this error. I was instructed to report it here.
Created attachment 11965 [details] my ide.log file for my installation of NetBeans
reassigned to the java module.
From the log I can read that you encountered the same error during two sessions of ide. Does it mean that you can reproduce it? For now it is too vague to determine where is the problem. I would recommend you to enable the memory meter in your main toolbar and watch during what steps memory is allocated and not released. BTW do you use internal compilation? How large is your source path (number of files in the filesystems tab and their size)?
I haven't seen the bug since reporting it here. I have no idea how to reproduce the bug. I was taking a stab in the dark that it might have been related to leaving NetBeans running for days at a time. I don't know if I use internal or external compilation. I believe I use external compilation (how would I know? When I select the Build-?Compile All menu option, nothing tells me what kind of compiler is being used.) The project this occurred on was around 1000 source files. Those source files depended on 7 .jar files located on a remote server. Each jar likely includes 100 or more classes.
To find out what compiler you use as default look at Menu/Tools/Options/Editing/Java Sources/Default Compiler.
I was right. I do use External Compilation.
Hmm, so nothing strange what could show where the problem is (java or other module). For now I close this as works for me. Feel free to reopen the issue if you encounter it again. Thanks
