Description
There are cases when the generated Java code exceeds Java limits and module compilation will fail with an exception like:
2019-09-12 10:46:28.206-0300 [main] ERROR com.streambase.sb.sbd.SBD - CompilationException: Runtime exception: ExecutionException: JaninoRuntimeException: Code of method "fieldMethod0(Lcom/streambase/sb/Tuple;Lcom/streambase/sb/runtime/CaptureManager;Lcom/streambase/sb/runtime/RuntimeEnv;[Lcom/streambase/sb/Schema$Field;Lcom/streambase/cache/SharedDataClass_5F37CC335F409A45CED2D8EB5E0BDDBF;)V" of class "com.streambase.cache.translationUtils_5F37CC335F409A45CED2D8EB5E0BDDBF" grows beyond 64 KB
The typical cause of this failure is a very large schema definition, or an operator (Map/Filter/Query) that evaluates many large expressions.
Environment
All supported platforms
Resolution
When this error occurs these system properties can be used to force the generated code to be refactored to work-around the Java limits:
In 7.7.x, these properties could be included in .sbconf:
For more details on these settings, please refer to the Help under Home > StreamBase References > StreamBase Java Properties
| System Property | Values | Description |
streambase.codegen.allow-refactoring | true to enable refactoring, false to disable. Default value is false. | Enable refactoring. |
streambase.codegen.n-stmts-limit | Positive integer > 1. Default value is 300. | Maximum number of statements in a block. streambase.codegen.allow-refactoring must be true. |
<java-vm>
<sysproperty name="streambase.codegen.allow-refactoring" value="true"/>
<sysproperty name="streambase.codegen.n-stmts-limit" value="200"/>
</java-vm>
For 10.x, when launching the fragment from studio, these are set on the Advanced tab of a Studio launch configuration:
-Dstreambase.codegen.allow-refactoring=true -Dstreambase.codegen.n-stmts-limit=200 -Dstreambase.codegen.broken-method-names=<Comma-separated list of fully-qualified-method-name:refactor-value or simple-method-name:refactor-value values>The refactor-value must be less than the value of
streambase.codegen.n-stmts-limit. Maximum number of statements in a block for a specific method.For more details on these settings, please refer to the Help under Home > StreamBase References > StreamBase Java Properties
