Reason
The Oracle SQL Developer installed in Oracle 11g is 32-bit, and the java.exe we are assigning to him now is 64 bits, so this error can occur.
Workaround
1) Download Oracle SQL Developer x64 from the web and replace the original directory: D:\app\oracle\product\11.1.0\db_1\sqldeveloper 32-bit Oracle SQL Developer. This will restart the Oracle SQL Developer and make the Java.exe path.
2) Install JDK6 x86, which is 32-bit JDK, although our system is 64-bit, but also compatible with 32-bit JDK.
