Description
FULL PRODUCT VERSION :
A DESCRIPTION OF THE PROBLEM :
A zero variant build of the latest OpenJDK 9 dev forest fails on 'java -version' with:
CICompilerCount of 0 is invalid; must be at least 1
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Since zero is a non-JIT JVM it should not need any just-in-time compiler threads. Byte codes get interpreted by the C++ Interpreter.
This is a recent local zero build of the OpenJDK 9 dev forest[1]. Specifically revision 783309c3a1a6 of the hotspot repository.
[1] http://hg.openjdk.java.net/jdk9/dev
THE PROBLEM WAS REPRODUCIBLE WITH -Xint FLAG: Did not try
THE PROBLEM WAS REPRODUCIBLE WITH -server FLAG: Did not try
REGRESSION. Last worked in version 8
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. build latest forest of jdk9 dev: http://hg.openjdk.java.net/jdk9/dev using the zero variant
(--with-jvm-variants=zero)
2. java -version fails to run
EXPECTED VERSUS ACTUAL BEHAVIOR :
Actual Results:
CICompilerCount of 0 is invalid; must be at least 1
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Expected Results (something along the lines of):
openjdk version "1.9.0-internal-debug"
OpenJDK Runtime Environment (build 1.9.0-internal-debug-sgeholf_2014_04_28_11_14-b00)
OpenJDK 64-Bit Zero VM (build 25.0-b62-debug, interpreted mode)
REPRODUCIBILITY :
This bug can be reproduced always.
CUSTOMER SUBMITTED WORKAROUND :
java -XX:CICompilerCount=1 -version works as expected for zero JVMs.
