Does JNI differ in JRE 1.4 and JRE 1.6 ? Our lib now crashes_问答_开发者

I'm responsible for maintaining a java swing application. It used to run quite fine with java 1.4, but with the time we encountered more and more crashes of the JRE that made us upgrade to the JRE 1.6, which at least is still maintained by Sun.

With the JRE 1.6 we now encounter a different kind of problem, in the part displaying ECW image files thanks to JNI and the native dlls NCSEcw.dll, NCSUtil.dll and NCScnet.dll (which are produced by ERDAS and can be found here : http://www.erdas.com/Products/ERDASDownloads/tabid/192/CurrentID/2560/Default.aspx ).

Most of the time the problem is a freeze (probably a deadlock) but one or two times we had real crashes of the JRE, with the hs_err_pid message I copied below. It does not appear on all machines, and is not systematic on the concerned machines (though very frequent). Most of the concerned machines seem to be running Windows 2000 SP4, but it appeared also on some XP machines and I can't find the criterion which differentiates them.

Is there a difference in the way JNI calls the library that make it work with 1.4 and not with 1.6 ? I'm a bit lost, thanks for any clue.
