Running regression on 1.4.2_06 build 1 the test for bug 4937429 failed.
This test compares the cacerts file in jre/lib/security and jre/javaws.
In 1.4.2_06 these are different but checked 1.4.2_05 b04 and the files are the same so it's a regression from 1.4.2_05 to 1.4.2_06.
To reproduce the test install 1.4.2_06
Go to <JAVA_HOME>/jre/lib/security and check the size of the cacerts file
Go to <JAVA_HOME/jre/javaws and check the size of the cacerts file
The two files are a different size. In 1.4.2_05 these files were the same size.
This bug has been seen on WindowsXP, RHEL 3.0 and Solaris 9x86 so far so it looks like it's all platforms
