The jre version in the .install directory is "1.4.2_04-b05" 
(/net/sgtpepper.sfbay/export5/s9orion2_nightly/orion1of2_sparc.s9_orion2/latest/Solaris_sparc/.install/j2se_jre/bin 37 % ./java -fullversion
java full version "1.4.2_04-b05"

EVALUATION If the issue as reported within the bug description is fully reproducible then based on the exception stack trace and the J2RE version being used by the installer 1.4.2_04 b05 it is possible that a bug within the sun.io.ByteToCharGB18030 is responsible for the crash. However, the evidence within the exception stack trace points to the sun.io retired converter being used when run in zh_GN.GB18030 locale instead of the (preferred) nio based charset implementation (sun.nio.cs.ext.GB18030). If this is the root cause of the bug then it is very likely that 4838512 (fixed/integrated in 1.4.2_05 and available in 1.5.0 beta b40 and higher) would prevent this bug from ever occurring. ###@###.### 2004-04-23 Although there is clearly a bug within the sun.io GB18030 decoder the issue reported is taken care of by availing of 1.4.2_05 or later where 4838512 addresses this issue ###@###.### 2004-04-26
