--------------------------------------
Summary: Compiler should fail for invalid targetBytecode values
Key: GROOVY-10595
URL: https://issues.apache.org/jira/browse/GROOVY-10595
Project: Groovy
Issue Type: Bug
Components: Compiler
Affects Versions: 4.0.2
Reporter: Lóránt Pintér
When calling {{CompilerConfiguration.setTragetByteCode()}} with an invalid
value, the user could be left thinking they set the value properly, when they
didn't. One example is using {{"8"}} instead of the valid {{{}"1.8"{}}}. If the
method failed for invalid values it would be easy to detect such a problem.
Note that this problem is mostly hidden for Groovy 3, where Java 8 is the
default target bytecode version. However, in Groovy 4 the target bytecode
version defaults to the Java version being used. Setting this value to {{"8"}}
thus results in the expected behavior in Groovy 3, but produces incorrect
behavior in Groovy 4 when used with a Java version other than 8.
