Java[TM]:Error occurred during initialization of VM java.lang.NoClassDefFoundError: java.lang.Object (Doc ID 1006790.1)

Last updated on AUGUST 17, 2017

Applies to:

Java SE JDK and JRE - Version 1.3.1 to 8
All Platforms

Symptoms

When trying to run a Java[TM] application, you get the following error message:

Error occurred during initialization of VM
java.lang.NoClassDefFoundError: java.lang.Object

Changes

Actions that are known to trigger this problem:

1. Trying to run a 64-bit JVM[TM] on Solaris (SPARCv9 or x64) when the required 32-bit JVM is not installed (does not apply to JDK 8 and later since starting with JDK 8 there is No 32 bit JVM anymore).

2. Removing the file rt.jar from the JVM installation folder, implicitly or explicitly. Third-party anti-virus software has been known to cause this problem on Microsoft Windows platforms.


3. Lack of read access rights to the file rt.jar.

4. Using the JVM's -Xbootclasspath: switch to modify the search path of the bootstrap class loader and Not including the file rt.jar on the search path.
