PQ51611: RSA APPLET BAD PERFORMANCE WITH IBM JDK 1.3.0_01 PLUGIN

APAR status

• Closed as program error.

Error description

• The RSA Signed applets are taking a long time to load with IBM
  JDK 1.3.0_01 plugin. The Security checking is done for each and
  every class. You can observe the security checking taking place
  for each and every class when you set the trace level to 3 in ja
  va console of the Netscape 6.0 browser. The same problem is bein
  g observed with SunJDK 1.3.0_01,1.3.0_02,1.3.0_03 versions of pl
  ugins. But the problem does not exist in base versions i.e,
  SunJDK 1.3.0 & 1.3.1 Plugins.
  

Local fix

• Currently IBM JDK 1.3.0 ships 1.3.0_01 version of plugin. Protec
  tion Domain Cache was removed in 1.3.0_01 plugin because of a
  security hole. That's why it is taking longer time to load signe
  d jar files because protection domain must be determined for
  each single class. This issue has been taken care now by introdu
  cing a smarter cache.
  

Problem summary

• as above
  

Problem conclusion

• apply any version of java with a build date
  of 20010825 or later to obtain the fix.
  

Temporary fix
