Becoming the owner of Java, Oracle unwittingly broke Eclipse

this month (post from July 28 — approx. lane), Oracle has released a new version of Java, 1.6.0_21 (6u21). Unfortunately, users of Eclipse was rapidly discovered that this version is incompatible with Eclipse software Eclipse Rich Client Platform (RCP).

Bug 319514 from eclipsemusic the bug tracking system contains the description of this problem with the print screen of the shell, in which it was clear that Oracle changed the company name in the settings file java.exe “Sun Microsystems, Inc” to “Oracle”. This change was not included in the official release notes. Ironically, Eclipse 2007 and was tied to this option to solve the other problems associated with the small value of the parameter “MaxPermSize”, set the Sun, causing Eclipse just does not start. But when the environment changed, and this fix also stopped working and many of them had problems with the “PermGen”.

It Oracle on Monday said update version 6u21, which returns the previous value. In addition, it was clearly stated that in JDK 7 in the field of the company will be mentioned “Oracle”. Here is what one of the developers:
One of the stages of a rebranding of all products and Sun products and Oracle', was that it was necessary to change the setting Company Name for file java.exe that was done in Java SE 6u21.

After the new version was posted on сайтеjava.sun.com we received many statements that the new changes have affected the user experience of Eclipse on Windows. All data and workaround problems were immediately pointed at the Eclipse, but the rapid spread of the new versions have affected all new and new users. Realizing this, and taking into account the wishes of Eclipse and many thousands of users, Oracle has restored the value of the parameter Company Name to “Sun Microsystems”.

The changes affected only the Windows version, while the version for Solaris and Linux worked fine. For the sake of this it worked and in Windows, was released a new build where the version was changed from 6u21-b06 to 6u21-b07. Under Solaris and Linux still came build 6u21-b06.

The division of engineering noted that: in Java, values of the parameter the java.vendor and java.vm.vendor will not change in any of the jdk6 releases and will remain “Sun Microsystems, Inc.”. It was found that the name of the provider in a critical impact on the performance of a number of programs. And in Windows a problem has been clearly specified for the. exe/dll field “COMPANY”, which was the source of the problem. In General, for us it was a big surprise that someone actually ties in such settings. Given this, for releases of jdk6 the COMPANY field was restored. But in the jdk7 releases will be the final change of all parameters, indicating the name of the company, including java.vendor and java.vm.vendor.

This morning, I was convinced that official download page posted a version that works with Eclipse. That would be issued on the screen in the command line when invoking java-version:

C:\> java-version
java version "1.6.0_21"
Java(TM) SE Runtime Environment (build 1.6.0_21-b07)
Java HotSpot(TM) 64-Bit Server VM (build 17.0-b17, mixed mode)

If you downloaded Java for 32-bit or 64-bit version of Windows, make sure that this version is called 1.6.0_21-b07, b06 and not.

ODBC Firebird, Postgresql, executing queries in Powershell

Изображение
Sometimes, system engineers may need to obtain specific data directly from the DBMS by means of Powershell. In this article I want to demonstrate two methods of operating firebird, postgresql through the odbc driver and client library. let's Start with the firebird and work with the database through the ODBC driver, you first need to register in the system client library GDS32.DLL, its bit width should be the same as the ODBC driver which should be installed next, download on the manufacturer's website , be sure during installation you need to tick on the registration of the library. Next install itself ODBC, who also take on the manufacturer's website , do not forget that the bit size should match the bit count of a previously installed client. Now actually have a powershell script, it was based on example in C# for postgresql. the $dbServerName = "localhost:base.gdb" $dbUser = "SYSDBA" $dbPass = "masterkey" [string]$s...

Installation LivestreetCMS on MODX Revolution package 10 clicks

Изображение
I have often written about your module modLivestreet for a bunch MODX Revolution + LivestreetCMS (In this Topeka in detail the idea and implementation of schemes, etc.). After almost two weeks since the beginning of the module development, I came to the following conclusion: it is too hard work. The idea itself is simple: MODX Revolution (which historically do not have enough modules for creating blogs) to tie LivestreetCMS in order to get the kind of sociolosko with good functionality. The first package I have thrown fast, and ensures the redirection of queries to Livestreet and output content in MODX. But then I tried to implement the synchronous operation with users of MODX - and LS-., and then something else... In General, the functionality grew, the code is also. The problems manifested in the difficulties settings of this Union. If MODX is possible to say in General, no serious problems have arisen (or at least did not have to touch a single byte code engine), then Lives...

The Ministry of communications wants to ban phones without GLONASS

Today in the Ministry of communications submitted the bill , according to which in Russia it will be possible to use only those mobile phones that include support for the GLONASS navigation system. Although it is not clear how this will be monitored, most likely, we are talking about banning the importation and sale. This decision was taken in order, and I quote in order to ensure the stability of the unified telecommunication network of the Russian Federation in various conditions. Requirements (in the case of the adoption of this act) will apply to manufacturers and sellers. To monitor the implementation of law be entrusted to Roskomnadzor. How has this come? For me personally this news is not very surprising (and not only because this is another project state silly the Duma), not so long ago there was another similar initiative, the essence of which was to translate public transport to use the system "To the end of the year practically the whole of Moscow is covered ...
