Indeed, it is fixed even in GCC 4.0.x. Now, is there any customer request or something that would justify changing GCC 3.4.x Java? We include GCC 4.0.x Java starting with RHEL4 U2, so if somebody really needs this, he can use that. But there are many known Java deficiencies in GCC 3.4.x Java I guess... gcc4-4.0.2-9.EL4 built in dist-4E-qu-candidate. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on the solution and/or where to find the updated files, please follow the link below.
