Out of memory after activating Blaze-Permission

See original GitHub issue


After activating BP i get a OOM heap exception on a test. This tests writes about 70k records batched:

    Lists.partition(allPermissions, 1000).forEach(chunk -> {

allPermissions is a Collection of PermissionCache` entries looking like this

@EqualsAndHashCode(onlyExplicitlyIncluded = true)
@NoArgsConstructor(access = AccessLevel.PRIVATE)
public class PermissionCache
  PermissionCacheId permissionId = new PermissionCacheId();

  public PermissionCache(final Long spaceId, final Long uid)

And the EmbeddedId is

@EqualsAndHashCode(onlyExplicitlyIncluded = true)
public class PermissionCacheId implements Serializable
  @Column(name = "space_id", columnDefinition = "INT(11)")
  private Long spaceId;

  @Column(name = "uid", columnDefinition = "INT(11)")
  private Long uid;

I’am using batched writes with

useServerPrepStmts=false&rewriteBatchedStatements=true on the JDBC URL and
# suppress inspection "SpringBootApplicationProperties"

In the properties

I understand that batch size can be one of the reasons here - but since that code has never thrown an OOM ever yet, and does so with BP, i suspect a memory leak we are yet not aware of

Expected behavior

Perform the same way as without BP

Actual behavior

OOM exception

  org.springframework.jdbc.datasource.init.UncategorizedScriptException: Failed to execute database script; nested exception is java.lang.OutOfMemoryError: Java heap space

  Caused by: java.lang.OutOfMemoryError: Java heap space

Full stacktace:

Steps to reproduce

Probably use the describe Entity with a simple JpaRepository (save/saveAll not overriden) Write arround 70k entries batched in one session


Version: 9.9-snapshot based on non-HEAD #846 JPA-Provider: hibernate 5.4.5 DBMS: mariadb10.3 Application Server: spring boot 2.1.7

In spring data 1.x CrudMethodMetadataPopulatingMethodInterceptor was implemented as singleton and I simply tried to do it like spring data did it. I’ll fix that.

This fixed this oom and nothing else broke on our side! Thank you
