Sometimes `arraycopy: length -XXX is negative` is raised

[Mingun]

Sometimes I get the following exception in my company's utility (length is varied):

java.lang.ArrayIndexOutOfBoundsException: arraycopy: length -5774 is negative

Unfortunately, cannot say what exactly data causing this because this is trace viewer utility and bug is appeared on big files. Probably the bug is related to the Message column in our utility, where variance of data is very high.

The latest 5.5.4 release is used.

The code that initializes TableFilterHeader:

JTable table = new JTable(new DataTraceModel(dataset.getEvents())) { ... });
final TableFilterHeader filter = new TableFilterHeader(table, AutoChoices.ENABLED);// TablePanel.java:1009

Hi, Mingun, Looking at your stack trace, I can see that the problem starts on a separate thread, is that the case? Normally, all Swing operations should be handled by the UI thread, using SwingUtilities' invokeLater or invokeAndWait, is it possible that there are multiple threads in place, not correctly synchronized with the II thread?? Best, Lu.
