getting this error when I include an opensource library that I had to compile from source. Now, all the suggestions on the web indicate that the code was compiled in one version and executed in another version (new on old). However, I only have one version of JRE on my system. If I run the commands: $ javac -version javac 1.5.0_18 $ java -version java version "1.5.0_18" Java(TM) 2 Runtime Environment, Standard unsupported class version error android studio Edition (build 1.5.0_18-b02) Java HotSpot(TM) Server VM (build 1.5.0_18-b02, mixed mode) and check in Eclipse for the properties of the java library, I get 1.5.0_18 Therefore, I have to conclude something else, internal to a class itself, is throwing the exception?? Is that even possible? java version share|improve this question asked Mar 18 '10 at 0:16 grmn.bob 6782611 2 do you have a compiled version of the library somewhere else that might be on your classpath first? –Jeff Storey Mar 18 '10 at 0:45 Good idea, but no. I did a check by using 'find . -name '*.jar' | xargs locate' from the lib folder with the JARs. Besides, I didn't think Eclipse used CLASSPATH? Any other good suggestions? –grmn.bob Mar 18 '10 at 1:13 how to use this find -name '*.jar' command on cmd as i am looking to rebuild the jre src code again...and for that i need to fire this cmd.....javalobby.org/java/forums/t103334.html.....my jdk is at C:\Program Files\Java\jdk1.6.0_31 –Java Geek Apr 22 '12 at 16:26 add a comment| 10 Answers 10 active oldest votes up vote 178 down vote accepted I've learned that error messages like this are usually right.

and version numbers associated with it and finally how to resolve UnsupportedClassVersionError in Java.

If you have not read those article you may find them useful. How to resolve UnsupportedClassVersionError in Java What is UnSupportedClassVersionError in Java? Java.lang.UnsupportedClassVersionError is a subclass of java.lang.ClassFormatError. This is a kind of linking error which occurs during linking phase accordingly java.lang.ClassFormatError has also derived from http://javarevisited.blogspot.com/2011/07/javalangunsupportedclassversionerror.html java.lang.LinkageError. As the name suggests "UnSupportedClassVersionError" so it's related to unsupported class version, now questions comes what is class version in Java? Well every source file is compiled into class file and each class file has two versions associated with it, major version and minor version. The Version of class file is represented as major_version.minor_version. This version is used to determine format of class file in Java. According to Java Virtual Machine specification, "A JVM implementation can support a class file format of version v if and only if v lies in some contiguous range Mi.0 v Mj.m. Only Sun can specify what range of versions a JVM implementation conforming to a certain release level of the Java platform may support." For example: JDK 1.2 supports class file formats from version 45.0 to version 46.0 inclusive. So if a class file has version 48.0 it means that major version of class file is "48" and minor version is "0", which tells us that JDK 1.4 has been used to com

A Windows error is an error that happens when an unexpected condition occurs or when a desired operation has failed. When you have an error in Windows, it may be critical and cause your programs to freeze and crash or it may be seemingly harmless yet annoying.
A stop error screen or bug check screen, commonly called a blue screen of death (also known as a BSoD, bluescreen), is caused by a fatal system error and is the error screen displayed by the Microsoft Windows family of operating systems upon encountering a critical error, of a non-recoverable nature, that causes the system to "crash".
One of the biggest causes of DLL's becoming corrupt/damaged is the practice of constantly installing and uninstalling programs. This often means that DLL's will get overwritten by newer versions when a new program is installed, for example. This causes problems for those applications and programs that still need the old version to operate. Thus, the program begins to malfunction and crash.
Computer hanging or freezing occurs when either a program or the whole system ceases to respond to inputs. In the most commonly encountered scenario, a program freezes and all windows belonging to the frozen program become static. Almost always, the only way to recover from a system freeze is to reboot the machine, usually by power cycling with an on/off or reset button.
Once your computer has been infected with a virus, it's no longer the same. After removing it with your anti-virus software, you're often left with lingering side-effects. Technically, your computer might no longer be infected, but that doesn't mean it's error-free. Even simply removing a virus can actually harm your system.
