Summary: OutOfMemory if filesize are greater than 7 MB
Product: Ant
Version: 1.6.2
Platform: PC
OS/Version: Windows 2000
Status: NEW
Severity: normal
Priority: P1
Component: Build Process
AssignedTo: dev@ant.apache.org
ReportedBy: michael.gellner@finanzit.com
Dear community,
sorry, I guess I found some trouble on ant 1.6.2.
I tried a replace operation (conversion from ASCII coded files to ANSI coded
files, i.e. in our case converting only around a dozen symbols in a large
amount of small to middle sized files).
The replace built failed always, if files became accessed that were bigger
than 6.5 MByte. This could be reproduced. An OutOfMemory exception occured. I
checked this with certain files to exclude the case that certain symbols or
something like that was responsible. It is definitely the filesize that causes
the crash.
Further on:
I process directories file by file. If there is a number of files processed,
this crashing exception occurs even in files that are significantly smaller
than 6.5 MB (my smallest observation was a crash on a 4 MB file in a directory
structure with around 16 000 files that add to around 500 MB).
And on:
If I combine the replace task with a copy task (first copy, than replace on
the backuped structure mentioned above) the built already crashes on the copy
task. Again with the java side OutOfMemory exception. I tried this with Java
SDK 1.4.1 and SDK 1.4.2, as well as with Xmx2048 option. For that reason I am
sure that the problem is not really the available memory.
I hope someone is able to reproduce this findings and maybe to correct in some
later version.
