User Comments:
achirizzi: Ok, so  I just started up NetBeans and it is showing this problem which is relative to the file

hadoop/hadoop-hdfs-project/hadoop-hdfs/target/generated-sources/java/org/apache/hadoop/hdfs/protocol/proto/ClientNamenodeProtocolProtos.java

which you can find in the hadoop project (git checkout branch-2.7.1 if you want to test it). It's a generated file.
Anyway it should not happen to have an OutOfMemoryError for a file which is not even open in the editor!

achirizzi: The problem is that I have never opened or tried to open the file in the summary (ClientNamenodeProtocolProtos.java). 
Was it part of a project Netbens failed to open and requested me to repair it? I just skipped that part cause I was not interested in opening those projects at this time.

GUEST: This is an automatic message

twolf2919: I opened the "Action Items" window and it was running EasyPMD - which must have tried to evaulate this large file (1+mb) when this exception happened.




Stacktrace: 
org.openide.text.DataEditorSupport$Env$ME: The file datatables.min.js seems to be too large (1 Mb) to safely open. 
Opening the file could cause OutOfMemoryError, which would make the IDE unusable. Do you really want to open it?
