Why can't you revert? You need to use the same version of ireport ang jasperreports. Try to find the jasperreports jar on apex an change it.

Mistankenly I was using a .report made by de ireport 3.7.2. After use the same version for both ireport and jasperreport the problem has gone.

Same error for me. I'm trying to migrate from JR 3.1.2 to 3.5.1 15:59:32,654 ERROR [sTDERR] net.sf.jasperreports.engine.JRRuntimeException: Unknown hyperlink target 0 15:59:32,654 ERROR [sTDERR] at net.sf.jasperreports.engine.JRHyperlinkHelper.getLinkTarget(JRHyperlinkHelper.java:273) 15:59:32,654 ERROR [sTDERR] at net.sf.jasperreports.engine.base.JRBaseTextField.normalizeLinkTarget(JRBaseTextField.java:317) 15:59:32,654 ERROR [sTDERR] at net.sf.jasperreports.engine.base.JRBaseTextField.readObject(JRBaseTextField.java:381)
