javac coredumps

[Zhichao Hong]

Hi, 
Please help a new beginner,
I download jdk1.1.6 and installed on redhat linux 5.0.  When I type javac,
it just coredumps.  I didn't use tar zxvf file.gz to untar the jdk,
instead I use gunzip < file.gz| tar -xvf -
Is this a problem?

My computer is Intel motherboard and Pentium 233 MHZ.  

Please help me on this.
Thanks,
Zhichao
