We are trying to do benchmarking of JVM on our system using SPECJVM2008. It is seen that the pre-compiled Specjvm2008.jar is compiled with a higher version than JDK 1.4 but my system will understand only JDK-1.4 or lower. I looked out for procedure to compile SPECJVM2008 for my target but could not find any. Can anyone help me to cross-compile SPECJVM2008 ? Thanks.
SpecJVM2008 will not support JDK-1.4 b'cos it is written using JDK-1.5 and later and is not backward compatible
I refer you to retrotranslator
Executing:
java -jar retrotranslator-transformer-1.2.9.jar -srcjar SPECjvm2008.jar -destjar SPECjvm2008_14.jar -embed com.mycompany.internal
produces a JDK 1.4 compatible jar with SPECjvm2008.

While building the code getting package sun.security.action is not visible
Package sun.security.action is declared on module java.base, which does not export it to the unnamed module.
What should I do.
Kindly advice, Thanks in advance
Java 8 had no module system - everything is visible or just needs to get imported by archives in jdk (f.e. tools.jar).
Java 9 brought JMS and encapsulated some jdk classes.
In your case, see <JAVA_HOME>/lib/src.zip!/java.base/module-info.class:
exports sun.security.action to
java.desktop,
java.security.jgss,
jdk.crypto.ec,
jdk.incubator.foreign;
Your package isn't public but restricted to some other internal packages/modules.
There was a workaround by adding compiler option --add-exports=java.base/sun.security.action=ALL-UNNAMED at compile time to fix this limitation until version 16.
With version 17 and JEP 403 forget all hope:
It is not a goal to define new standard APIs to replace internal elements for which standard replacements do not yet exist, though such APIs could be suggested in response to this JEP.
Backwards compatibility and important frameworks have lower priority than jdk security - JCP makes strange decisions and works against the community sometimes -.-
I'm trying to switch from liquibase depedencies from 3.0.2 to 3.4.1 in a Java based tool but when running with Java 7 (tried different updates including latest 80) i'm getting strange exceptions like:
2015-11-13T11:55:43,351+02:00 ERROR java.lang.IllegalStateException: Cannot find generators for database class liquibase.database.core.MSSQLDatabase, statement: liquibase.statement.core.UpdateStatement#5232d51 - [pool-3-thread-1]
liquibase.exception.LockException: java.lang.IllegalStateException: Cannot find generators for database class liquibase.database.core.MSSQLDatabase, statement: liquibase.statement.core.UpdateStatement#5232d51
or
iquibase.exception.UnexpectedLiquibaseException: liquibase.exception.ServiceNotFoundException: liquibase.exception.ServiceNotFoundException: Could not find unique implementation of liquibase.executor.Executor. Found 0 implementations
at liquibase.executor.ExecutorService.getExecutor(ExecutorService.java:31) ~[liquibase-core-3.4.1.jar:na]
With Java 8 everything works fine.
Is this a known issue? Is there any documentation stating 3.4.1 works only with Java 8 (couldn't find anything).
Thanks,
Dan
It looks like you're experiencing the issue fixed in this bug report. If you upgrade to 3.5.x you should be okay.
I am trying to use ActiveMQ 5.10.0 with SoapUI 4.6 and Hermes 1.14. I get the error below when I try and add a queue. I presume Hermes can't find the type IdGenerator in any of the loaded jars. Which are:
activemq-client-5.10.0.jar
geronimo-j2ee-management_1.1_spec-1.0.1.jar
geronimo-jms_1.1_spec-1.1.1.jar
Does anyone know where this class is defined? I looked for activemq-util.jar in the binary distribution but I did not find such a file.

This is very old but in case anyone else is trying to get this spun up... don't use the built in HermesJMS that comes with SoapUI. Apparently there's a bug in it that doesn't play nice with ActiveMQ v5.8 and following [I tried 5.11 & 5.13 and had the issue. The cheating fix is to install the standalone [I had to get it from sourceforge].
The sourceforge jar is installed with [assuming version 1.14]: java -jar hermes-installer-1.14.jar
Once installed you can tie this version to soapui or launch it with the bat/sh file. I still had issues with ActiveMQ version 5.13 but version 5.11 worked for me.
The IdGenerator class is located in the activemq-client jar. Here is the result of a search in the source tree:
/activemq-client/src/main/java/org/apache/activemq/util/IdGenerator.java
There's been no recent changes so I'd guess that the error is misleading and that it's actually some other missing dependency that's being loaded when the class is created. Is there more information in the log or a 'caused by exception' ?
For whom it may interest. This is kind of common issue I come accross from time to time. I call it jar version incompatibility. I was getting exception in title and other funny exceptions when using latest (but not actively developed) hermes 1.14 and currently latest Apache Active MQ 5.14. I've found out after a long struggle that it is fixed by using an older version of Active MQ - like 5.3.
I am using Eclipse Kepler with jdk1.8.0.
I do not face any compilation problems in import statements related to java8 or collect construct. However I get the compilation issue in:- Dish::getName...it says.. Syntax errors on tokens, delete the tokens.
Just trying to run the following code:
List<String> dishNames = menu.stream()
.map(Dish::getName)
.collect(toList());
System.out.println(dishNames);
Dish is a java object with String property name.
I have installed JDK8, added the latest JRE in eclipse Java Build Path.
Java compiler compliance.
Any hints what something silly I am missing?
I think you missed installing support of java8 in eclipse kepler.
You can follow this link for detailed instructions.

I am using monticello's location as "http://source.squeak.org/FFI" and then trying to load FFI package for MacOS. I could load FFI-Pools,FFI-Kernel. But was unable to load FFI-MacOS, It throws error on "getenv" method. Synatx error:'>'expected. I think I am doing something wrong. Could someone direct me to appropriate link?
Thanks
In Pharo 3, use the configuration from Configuration Browser:
World Menu > Tools > Configuration Browser, then Install Stable Version.
All tests are green on OSX 10.9.
alternatively, you can execute this in your workspace:
Gofer it
smalltalkhubUser: 'Pharo' project: 'MetaRepoForPharo30';
configurationOf: 'FFI';
