[DataVision-users] [Fwd: [datavision - Open Discussion] RE: out of memory error]

[Jim M. <ji...@io...>]

I'm forwarding this to the group in case nobody checks the SourceForge 
discussion forums. Looks like a bug in StringUtils#wrapLineInto.

I don't have time right now to follow up or investigate this bug, beyond 
seeing that indeed the "while" clause does not terminate if no good breaking 
point is found in a really long string. If somebody can perform initial 
investigation, I'll try to answer any questions that come up.

A suggestion: write a unit test that fails first!

Jim

The wrapLineInto method os StingUtils.java in DataVision is causing the out
of memory.
I found that for some data the method is going to infinite loop.The data I checked
for ..."VILLA NO-E2,EPSILON,YEMLUR MAIN ROAD,".
I think the wrapping is based on the width of the column.For the particular
width and data it is going to infinite loop and throws out of memory error.

Please help me.
