[jira] Resolved: (DERBY-176) Derby throws ERROR XBCM1: Java linkage
error thrown during load of generated class
org.apache.derby.exe.aced07c066x0102xca87x3319x00004aa5686e1 during
execution of large query
[ http://issues.apache.org/jira/browse/DERBY-176?page=all ]
Daniel John Debrunner resolved DERBY-176.
-----------------------------------------
Fix Version/s: 10.2.1.0
10.3.0.0
Resolution: Fixed
Changes for DERBY-766 and under this bug ensured that a "Query too complex" exception is thrown if the resulting generated class will not be loadable by the JVM due to exceeding limits.

> When executing a large query or oather large operations, Derby throws a java linkage exception.
> This is because the generated byte code exceeds the JVM limits for method sizes constant pool entries etc, the amount of code in a conditional etc. The attached repro demonstrates the problem but the problem can also occur for other operations that generate lots of byte code. The repro is just a new functional test,
> so should be copied to derbyTesting/functionTests/lang/largeCodeGen.java and run like
> java -Djvmflags=-Xmx512M org.apache.derbyTesting.harness.RunTest lang/largeCodeGen
> When this problem is fixed additional scenarios should be added to this test.
