Re: memory allocation for JVM - "file too big to open safely" [netbeans] [java]
Hi, It is only a warning that the file maybe is too big. There are lots of configuration possibilities available for experiences users. Maybe a central page in the wiki which collects all the settings/properties would be fine. Is there such a collection somewhere? Where can it place in the apache netbeans site? Oliver I think the software program sucks if the software did not advise user in the error message to adjust the parameter. J-Dorg.openide.text.big.file.size=10.

Re: memory allocation for JVM - "file too big to open safely" [netbeans] [java]
Hi all, Neil is completely right - thanks for the hint. The warning is opened if a configurable maximum file size is reached. The default value for this is 1MB and can be increased by by adding system property, e.g. -J-Dorg.openide.text.big.file.size=10 I will think about to use this mechanism also for my scientific netbeans platform applications, if i open data files to be plotted. best regards Oliver > On Sun, 20 Dec 2020 at 16:25, Oliver Rettig wrote: > > I remember also got such messages in the past during opening big text > > files in my netbeans-platform applications and with increasing heap-size > > I cauld not get rid of the message.

It's probably this? https://github.com/apache/netbeans/blob/master/platform/openide.loaders/src/org/openide/text/DataEditorSupport.java#L853 Should be able to set that system properly to a MB value greater than 1 by the look of it.

Re: memory allocation for JVM - "file too big to open safely" [netbeans] [java]
Looking at this page https://stackoverflow.com/questions/13685402/how-to-assign-more-than-1gb-to-netbeans-jvm I suggest setting this parameter to see if you get the corresponding error message. when I set -J-Xmx3024m I obtain these messages: /opt/netbeans-7.2/bin/netbeans Error occurred during initialization of VM Could not reserve enough space for object heap Error: Could not create the Java Virtual Machine.Error: A fatal exception has occurred. Program will exit If you do then you know you are in the right place. This text suggests you can play around with the size. The message Could not reserve enough space for object heap means that 3024 MB is not available for assignment. Try reducing it Then you try this as suggested. netbeans_default_options="-J-client -J-Xss2m -J-XX:PermSize=512m -J-XX:MaxPermSize=512m -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -J-Dsun.zip.disableMemoryMapping=true -J-Xms2148m -J-Xmx2148m -J-XX:+UseParallelGC" On Sun, 20 Dec 2020, 16:25 Oliver Rettig, wrote: > Hi, > > > > I remember also got such messages in the past during opening big text > files in my netbeans-platform applications and with increasing heap-size I > cauld not get rid of the message.

Re: memory allocation for JVM - "file too big to open safely" [netbeans] [java]
Hi, I remember also got such messages in the past during opening big text files in my netbeans- platform applications and with increasing heap-size I cauld not get rid of the message. In my cases after closing the dialog all works fine. So I dont have a closer look at this. Maybe there is simple somewhere hardcoded a maximum file size and after reaching this size the dialog is thrown. I am also interested in, if you can fix this. best regards Oliver Hello, I am running NetBeans 12 in Ubuntu 14.04. When trying to load a file of text, I get the message "It seems that the file is too big to open safely...etc...". I have changed the netbeans.conf and app.conf files to include -J-Xms512m -J-Xmx2048m but I still get the error. I want to try increasing the allocation(s) for the JVM itself, but I can't find instructions to do that when you're using NetBeans, only for times when you're running "javac" and "java" commands in a terminal -- my installation doesn't recognize the "java" command - if it did I'd enter java -J-Xms512m -J-Xmx2048m Any suggestions? Thanks.

Maybe check in the IDE log (just after the line that starts "Input arguments:") to see if those options have truly been applied. Maybe NB has another limit that causes it to print that message, independent of the heap size. Hopefully someone who knows can answer that. Whenever I get that warning I just ignore it to be honest!
