the behaviour of one of the customer's methods changes after
the hotspot compilation has kicked in.

testcase decodes a base64 encoded byte array & compares with a
hardcoded array. this works with -client vm but seems to fail
after a number of iterations when using -server.

failures occurring on windows (98 & 2000) but don't seem to
happen on solaris.

teestcase is in /net/kelvin.uk/export/dts/calls/418357/rj
