I'm still verifying the jarsigner and the SecurityTools changes, but all of the other files actually need the EGD override.

test/jdk/java/security/SecureRandom/ApiTest.java line 56:

This test uses generateSeed and needs egd.

test/jdk/java/security/SecureRandom/EnoughSeedTest.java line 43:

This test uses generateSeed and needs egd to avoid reading from /dev/random

test/jdk/java/security/SecureRandom/MacNativePRNGSetSeed.java line 30:

this change makes this test pointless, see summary 2 lines above

test/jdk/java/security/SecureRandom/MultiThreadTest.java line 44:

This uses generateSeed and needs egd to avoid using dev/random

test/jdk/java/security/SecureRandom/Serialize.java line 36:

This uses generateSeed and needs egd to avoid using dev/random

test/jdk/java/security/SecureRandom/SerializedSeedTest.java line 32:

This uses generateSeed and needs egd to avoid using dev/random

test/jdk/sun/security/provider/SecureRandom/AutoReseed.java line 31:

This test uses generateSeed and needs egd to avoid reading from /dev/random

test/jdk/sun/security/provider/SeedGenerator/SeedGeneratorChoice.java line 29:

> 27:  * @summary NativeSeedGenerator is making 8192 byte read requests from

> 29:  * @run main/othervm -Djava.security.egd=file:/dev/random SeedGeneratorChoice

This test uses generateSeed and should be run with egd pointing to /dev/urandom to avoid reading from /dev/random
