Eric Milles commented on GROOVY-11205: -------------------------------------- In order to support type annotations (JSR 308), references to "int", "Object" and so on in your sources have to be new instances rather than shared references. There is a lot of state in a single ClassNode instance, most of which is for a type definition rather than a type reference. GROOVY-11159 discusses the possibility of separating the state somehow for purposes of memory savings. > Groovy 3.0.13 to Groovy 4.0.13, I encountered a "Java heap space" error > during the compilation process > ------------------------------------------------------------------------------------------------------- > > Key: GROOVY-11205 > URL: https://issues.apache.org/jira/browse/GROOVY-11205 > Project: Groovy > Issue Type: Bug > Components: performance > Affects Versions: 4.0.13 > Environment: openjdk version "17.0.6" 2023-01-17 LTS > OpenJDK Runtime Environment Corretto-17.0.6.10.1 (build 17.0.6+10-LTS) > OpenJDK 64-Bit Server VM Corretto-17.0.6.10.1 (build 17.0.6+10-LTS, mixed > mode, sharing) > WIN11 > Reporter: DuanHen > Priority: Major > Attachments: groovy_3_0_13_mem.png, groovy_4_0_13_mem.png > > > I'm facing an exception after upgrading the groovy-all version used for > testing in my Gradle project from 3.0.13 to 4.0.13. > > Task :compileTestGroovy FAILED > FAILURE: Build failed with an exception. > * What went wrong: > Execution failed for task ':compileTestGroovy'. > > Java heap space > The current temporary solution is to increase jvmArgs. > jvmArgs = ['-Xms512m', '-Xmx1g'] > ↓ > jvmArgs = ['-Xms512m', '-Xmx2g'] > I have created a validation project, analyzed the memory, and found an > increase in memory usage for org.codehaus.groovy.ast.ClassNode in version > 4.0.13, particularly when there are a large number of test classes. -- This message was sent by Atlassian Jira (v8.20.10#820010)
