updatemanager java run-time proboem

I typically invoke "updatemanager" remotely using Xwindows.I get this error message:

Exception in thread "main" java.lang.IllegalArgumentException: Null charset name at java.nio.charset.Charset.lookup(Charset.java.378) at java.nio.charset.Charset.isSupported(Charset.java:407)

I have applied a JES patch (117665-03) which would update the Directory Server 5.2 from patch level 3 to patch 4 recently. This might not be related but this change has been recently. I have already opened up an incident 64771370 in the past to get the DS components patched to the latest level. This might or might not be relevant. The DS components are very much java-based.

Please advise.
