[#3609] - JasperServer 5.5.0 truncates text

JasperReports Server of v. 5.5.0(I use it on Linux x64) truncates values both in column names and in detail. I can not understand it's logic, because text lenth is different (net.sf.jasperreports.text.truncate.at.char=false, net.sf.jasperreports.print.keep.full.text = true)
The fact is, I made a report in JasperSoft Studio 5.5.2 and it works there normal (it means, that my postgreSQL data base gives the report full values) without any truncation, but the same report published to the server provides truncated values. I suppose it's a bug.
