> salmansayyad: Problem
The heap size limit is too low (-Xmx386m) for running NetBeans.
Please increase it. See http://wiki.netbeans.org/FaqSettingHeapSize.

> GUEST: don't know, what I did 
Retained size of an instance of org.apache.tools.ant.module.bridge.impl.ForkedJavaOverride$Copier is 268 MB. Its currentLine (ByteArrayOutputStream) consumes most of this memory.

Reassigning to projects/Ant. Please evaluate.
Thank you.
Comment 3 Tomas Stupka 2015-05-29 14:14:22 UTC 
see AbstractLInes.getText(int start, int end)
the attempt is made to print a buffer into _one_ line 

In case of all (currently three) heapdumps it looks like the buffer contained many many many megabytes - e.g. in case of 751617 180mb were supposed to be printed into one untruncated line in the output view ...

> supposed to be printed into one untruncated line in the output view
Thank you, Tomas. Output View truncates long lines (if line wrap is off). The problem was that the string with last line contents was constructed, although just it's length was needed.

Fixed in http://hg.netbeans.org/core-main/rev/86b7fff062e5.
Comment 5 Quality Engineering 2015-08-07 01:16:30 UTC 
Integrated into 'main-silver', will be available in build *201508070002* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
