Hi,
I'm using the glibc version of jdk1.1.7v1a on a RH 5.2
system with glibc 2.0.7.
When trying to run some programs, I'm getting this message:
java.lang.Error: dtz null
at java.util.TimeZone.getDefault(TimeZone.java:94)
at
at
at ObjectSerialization.main(ObjectSerialization.java:8)
It also happens in the compiler:
java.lang.Error: dtz null

Here's the input with which it happens, save it as ObjectSerialization.java
The weird thing is that it happens only intermittently, though it's
reproducible for a given input.
I'm using green threads and no JIT, although it also happens with
native threads and TYA.
NB: the failure that happened when running the program was produced
after I compiled the .java file with Kaffe's pizza compiler.
More info, in case you're interested:

Any ideas? Is this a know problem?
Btw, is there a bug database for this jdk?
Thanks,
