Symptoms

When you try to start / re-start your OC4J (10.1.3.3.0) containing a WebService,
you see the following intermittent error in your logs:

java.lang.InstantiationException: Error compiling:
<ORACLE_HOME>/j2ee/<oc4j_name>/applications/<application_name>/my-WSS-1.0: Syntax error in source or compilation failed in:
<ORACLE_HOME>/j2ee/<oc4j_name>/application-deployments/myApp/my-WSS-1.0/<path>/myProgram_LiteralSerializer.java
Note: Some input files use unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

-----------------------

When you turn on debugging, you notice the following entries in your log:

10/07/20 14:15:11 Got javac ./<JDK_HOME>/bin/javac
10/07/20 14:15:12 Code Formating is set to true
10/07/20 14:15:12 Start Compilation using javac
10/07/20 14:15:12 Using External Javac Compiler...
10/07/20 14:15:12 Args: [/<JDK_HOME>/bin/javac, -J-Xmx1024m, -encoding, UTF8,
  <ORACLE_HOME>/j2ee/<oc4j_name>/persistence/<oc4j_name>_1/javac.params.*]

-----------------------

But when you navigate to the folder <ORACLE_HOME>/j2ee/<oc4j_name>/persistence/<oc4j_name>_1
you are unable to find javac.params.*.

You would like to know how to prevent the file javac.params.* from being deleted
